Complex Terminal Systems Design: Minimizing Time to Deployment

Welcome to the DATE 08 Conference Proceedings. DATE combines the world's favourite electronic systems design conference and Europe's leading international exhibition for electronic design, automation and test, from system level hardware and software implementation right down to integrated circuit design. The DATE 08 event features a technical program with 77 sessions covering the latest developments in system design and embedded software, IC design/test methodologies and EDA tools, together with an exhibition with the leading EDA, silicon and IP providers showing their new products and services. Challenges that you all face or soon will face in your daily practice are the increasing design complexity of highly integrated systems, the introduction of reconfigurability and embedded software, and the control of power and variability in nanometer IC designs. All these issues will be addressed in this year's DATE event. For the 11th successive year DATE has prepared an exciting technical programme, with the help of the more than 400 members of the Technical Programme Committee, who dedicated their time to thoroughly review the 839 submissions in 37 topics, ranging from system level down to circuit design and covering all the most relevant application domains. The submissions are organised in 4 major areas: D --- Design Methods, Tools, Algorithms and Languages A --- Application Design T --- Test Methods, Tools and Innovative Experiences E --- Embedded Software After a thorough review and selection process (with an average of 5 reviews per paper), finally 198 regular papers were selected for presentation at the conference. Additionally, there are 46 Interactive Presentations that are organised in 5 IP sessions. Together with the invited special sessions (panels, embedded tutorials and hot topic sessions), this has resulted in a high-quality technical program. The technical program provides a wide but high-quality coverage of design, design automation and test topics, from the system level to the integrated circuit level. Compared with previous years, submissions in the Embedded Software track has increased by 50%, showing a clear trend towards a comprehensive system design focus with integrated hardware and software solutions. DATE has established itself firmly as a true Electronic System Design Conference. This year the conference is held in Germany, at the ICM in Munich and spans an entire working week from Monday March 10 to Friday March 14. On Monday, eleven pre-conference tutorials will be given. The three-full day tutorials cover topics of great interest for system design. The first tutorial deals with techniques to automatically realising embedded system from high-level functional models. The second tutorial addresses the different issues related to communication based design and architectures in automotive electronic systems. The third tutorial discusses several key concepts on system-level design and application mapping for wireless and multimedia MPSoC architectures. Furthermore, eight half-day tutorials are also given, which cover a wide spectrum of topics on specification, modelling, design and test. The main conference opens on Tuesday March 11, with two very interesting and complementary keynote speeches. Dominique Vernay, Chief Technical Officer for Thales, will talk about the challenges of embedded systems design, and Giovanni de Micheli, Professor at EPFL, will present his views on designing micro/nano systems for a safer and healthier tomorrow. On the same day, the Executive Track offers a series of business panels with executives discussing hot topics in design: the perils of 45 nanometers, the changes in EDA strategies from IDM, to fablite to fabless, and embedded systems level design strategies. DATE 08 will again offer two specific days related to special themes. On Wednesday March 12, a special full-day track is devoted to Automotive Electronics---Software and Architecture. This special-day track will focus on the challenges faced by the automotive supply chain with particular attention to system and software architecture design. It provides a comprehensive analysis of the evolution of automotive architectures, including ECUs, sensors and communication standards and discusses how new methods, tools and standards for interoperability and component-based design can deal with the increasing complexity of software systems and their need for reliability and guaranteed timely behaviour. In addition, it addresses to what degree existing standards, including AUTOSAR and FLEXRAY and model-based development, can support the development of safety and time-critical software. On Thursday March 13, a second special full-day track focuses on Dependable Embedded Systems. This track will address both conceptual and applied issues for design, analysis and validation of dependable embedded systems. The utility of embedded systems and services is based, in large part, on our depending on their sustained functionality in spite of the encountered operational or malicious disruptions. As the number of transient and also permanent disruptions (given the decreasing device geometries, higher device density, lower voltage latching, faster clocks etc) is expected to increase substantially, this will not only be a key issue for the hardware community but also the systems community in general. Solutions using a combination of hardware and software might be more effective than hardware-only or software-only solutions. This track focuses on both conceptual and applied issues for design, analysis and validation of dependable embedded systems. Besides these special tracks, the main conference is organized in six parallel tracks of sessions, three devoted to design methods, tools, algorithms and languages, one to application design, one to test methods, tools and innovative experiences, and finally one to embedded software. The presentations of the selected regular papers in these parallel tracks are complemented by nine Special Sessions and two Invited Industrial Sessions. The special sessions are organized in the form of panels, hot topics, and embedded tutorials. The topics to be covered include quantitative evaluation for embedded systems design, design and manufacturing at 32 and 22nm, software for wireless networked embedded systems, test challenges for low power devices, quantitative productivity measurement in IC design, and 3D Integration. The two invited industrial sessions deal with industrial system designs in transportation and information technologies. To emphasise that DATE is the major event for the designers, DATE 08 features also invited sessions where Europe's famous consumer industry presents their best designs and design practices. Friday March 14 is the day for the DATE workshops. DATE 08 offers workshops on current and emerging important issues in design, test, EDA and software to complement the regular conference. They provide a unique opportunity for the various research and design communities to spend a day discussing the latest and the best, sharing their experiences and visions. This year's workshop program includes eight workshop themes. Four workshops are related to software engineering, ranging from dependable software to modelling, analysis and development tools. Four other workshop themes cover a variety of topics such as the impact of process variations on design and test, the merging world of Nano-Electro-Mechanical Systems, new directions in high level synthesis, and heterogeneous reconfigurable hardware. Each workshop features presentations, invited or submitted, from highly distinguished academic and industrial researchers. Finally, throughout the conference days, DATE offers a comprehensive overview of commercial design and verification tools in its large exhibition hall. Exhibitors include EDA vendors, silicon, FPGA and IP providers showing their new products and services. In addition, there is an Exhibition Theatre featuring talks from engineering managers of the leading electronic manufacturers on first-hand design experiences of commercial EDA tools. New this year is the European projects village where different European and large government funded projects will be able to show their ongoing research and results to the design community and have the opportunity for internal meetings and discussions. The DATE week will be also an opportunity for students and universities to show their research work, through the PhD Forum on Monday evening and the University Booth where hardware and software demonstrations will be shown by different universities on a rotation schedule. The DATE 08 event's program will be particularly attractive to industrial designers, at analog, IC, FPGA and embedded system level, as well as software designers, to researchers and academics as well as to design managers, and an increasing attendance is expected. We therefore invite you to take full advantage of the many opportunities offered to you by DATE 08, to extend your knowledge and/or business in electronic system's design and to exploit the abundant networking possibilities offered to socialise with colleagues, including fringe meetings and a memorable social party with bands and dancing. We hope that you will all enjoy the DATE 08 Conference and Exhibition.

Satellite communication is one of the key focuses of the sixth generation (6G) mobile communication systems, and aerial hybrid reconfigurable intelligent surface (AHRIS) -assisted satellite communication has recently emerged as a promising candidate for practical deployment in the 6G wireless networks. System design and gain rely heavily on accurately modeling of the underlying channel characteristics, which is challenging due to the high mobility of AHRIS and the unique properties of satellite communication. In this paper, we propose a novel three-dimensional (3D) non-stationary wideband geometry-based stochastic model (GBSM) for AHRIS-assisted satellite communication systems, where AHRIS movements and satellite trajectories are specifically considered. Moreover, two AHRIS phase correction schemes are proposed based on the characteristics of AHRIS in satellite communication systems. Following this, channel correlation function, Doppler power spectral density (PSD) and channel capacity are derived according to the proposed model. Simulation results show that the proposed model can accurately capture the characteristics of the AHRIS-assisted satellite communication systems, and the proposed phase correction schemes can effectively improve the channel statistical characteristics and increase the system capacity.

Satellite communication (SATCOM) system is to be applied in the communication, oceanographic, and meteorological satellite (COMS). ETRI has completed the preliminary design effort for the SATCOM project - an effort which included clarifying requirements, refining mission description and operation, determining the configuration of the payload, and anticipating subsystem performances, schedules, costs, and so on. This paper includes an overview of the project work, and the preliminary design of the Ka-band on-board switching transponder in point of RF performances. A recommendation for future work is also included to aid subsequent projects associated with SATCOM system

In this paper, we have developed a machine learning based adaptive predistorter for high power amplifier linearization approach under dynamically changing environment. In the “bent-pipe” transponder in satellite communication (SATCOM) system, the High Power Amplifiers (HPAs), which are similar to other amplifiers in the communication system, can cause nonlinear distortions to transmitted signals, deteriorating the system transmission performance. The traditional model based processing techniques such as the Extended Saleh's Model (ESM) based predistortion design can be applied to maximize transponder throughput along with HPA power efficiency but sensitive to dynamically changing environment. In this paper, the compensated HPA linearity characterized through Amplitude Modulation-to-Amplitude Modulation (AM-AM) and Amplitude Modulation-to-Phase Modulation (AM-PM) effects is used as the system reward, we leveraged reinforcement learning approach to dynamically optimize the parameter set for the ESM based PD to improve system performance in various environmental conditions. Finally, simulation results are provided to evaluate and verify Bit Error Rate (BER) improvement for the considered SATCOM system by applying our proposed PD technique.

Daylight Solutions has pioneered the development and commercialization of quantum cascade laser (QCL) technology for commercial and military markets. Multi-Watt, multi-wavelength QCL-based systems have been manufactured and tested against harsh military environmental requirements for military applications. These self-contained, turn-key systems have been designed to comply with modular open system architecture (MOSA) principles, and have been proven in several different system geometries. This paper will highlight the environmental requirements imposed upon, and performance from, QCL-based laser systems for example military applications.

Monofilar and multifilar helical antennas are the most widely proposed antennas in satellite communications systems. The main reason why these antennas constitute an asset in applications concerning satellite and space communications generally is circular polarization. Good axial ratio provides precise measurement of the polarization of the received signal due to immunity of the circularly polarized wave to Faraday rotation of the signal propagating through the ionosphere. In addition to circular polarization, monofilar helical antennas offer the advantage of high gain in axial direction over a wide range of frequencies which makes them suitable for applications in broadband satellite communications.

Low Earth Orbit (LEO) satellite communication systems have evolved into a critical component of global broadband networks, enabling wide‐area connectivity, IoT services, and intelligent multilayer satellite–terrestrial integration. Despite rapid advancements in constellation deployment, routing mechanisms, resource management, and LEO–5G/6G convergence, the long‐term evolution of research themes and network architectures remains insufficiently mapped. This study analyzes 2420 Web of Science articles published between 1995 and 2025 and applies bibliometric techniques, main path analysis, and edge‐betweenness clustering to identify the core technological trajectories shaping the LEO communication domain. The results reveal five major phases of development: foundational constellation design, multilayer architecture integration, performance and QoS optimization, 6G‐driven intelligent connectivity, and secure collaborative networking. Four dominant research clusters emerge: communication and IoT applications, routing and topology management, satellite edge computing and task offloading, and LEO‐enhanced GNSS positioning, highlighting the field's structural diversification. Main path and key‐route analyses further show a gradual shift from traditional connectivity‐oriented engineering toward distributed, AI‐enabled, and security‐aware satellite communication frameworks. This study provides the first longitudinal mapping of LEO communication research, offering an integrated understanding of how architectural evolution, protocol innovation, and emerging intelligent services intersect. The findings support future advances in satellite networking, resource optimization, and the design of resilient and interoperable LEO systems.

Satellite communication technology has become a research hotspot in today's society because of its important significance to the development of modern society. However, the realization of satellite communication is a big project with high difficulty and high cost. Therefore, it is necessary to use computer software to model the satellite communication system and further understand the satellite communication scenarios and communication links. Based on the basic theory of LEO communication satellite, this paper uses STK software to complete the modeling of traditional satellite communication system, and realizes the visual simulation of LEO satellite communication. Finally, through the analysis of the simulation process and simulation results, the connection rate of normal communication between ground stations is calculated.

Provides an update to the developments associated with a prognostics and health management (PHM) system design tool that integrates a model-based FMECA methodology with state-of-the-art system simulation directly linked to downstream life cycle costs (LCC). This design tool will seek out recommended PHM system designs based on a cost function that accurately represents key LCC variables such as system availability, maintainability, reliability, and failure mode observability. The tool will be capable of assessing PHM sensor requirement specifications at the component and subsystem levels, and will then allow for integration into a broader integrated system model. Tradeoff, sensitivity and what if analysis will then allow the designer/user to examine the cost/benefit relationship of either adding or removing sensor and algorithms under consideration for the PHM design. A simplified example of a health management system cost/benefit analysis on an aircraft electromechanical valve is provided for illustration of the concepts introduced.

Spread spectrum communication technology is one of the most critical core technologies in anti‐jamming satellite communication systems. However, it has certain technical limitations in anti‐jamming applications. For instance, frequency‐hopping spread spectrum technology exhibits weak resistance against spot jamming, while direct‐sequence spread spectrum technology is less effective in mitigating wideband interference. With the continuous development of satellite countermeasure technologies, these technical limitations will significantly constrain the performance of satellite communication systems and compromise the reliable transmission of space‐based information. Aiming at the technical limitations of spread spectrum anti‐jamming satellite communication, this paper proposes a solution based on blind source separation technology to enhance the anti‐jamming capability of spread spectrum communication. This paper establishes a blind source separation‐based anti‐jamming communication prototype system, verifying the feasibility of applying blind source separation to communication anti‐jamming. It conducts an in‐depth analysis of the characteristics and existing issues in spread spectrum anti‐jamming satellite communication systems, identifies the problems and challenges of applying blind source separation to such systems, and proposes potential solutions.

For the past 25 years the effects of the polar ionosphere on satellite communications has been under evaluation in Greenland. As a result of the testing, models have been developed which quantify the effects of solar flux, magnetic index, time of day, season, elevation angle, and frequency on ionospheric scintillation fading. For the past 10 years, operational type of satellite communications testing has been conducted in Greenland to evaluate the feasibility of replacing the traditional HF radio links with satellite communications links. This paper reviews the effects of polar ionospheric scintillation fading, describes the operational testing, and identifies plans for operational use of satellite communications in Greenland.

Under the condition that satellite communication resources are limited, how to ensure the high efficiency to ensure satellite communication tasks is one of the key issues facing satellite communication systems. This article mainly introduces satellite communication tasks facing different task levels. Based on the improved GA algorithm, based on the analysis of satellite communication task parameter sets, it constructs satellite communication tasks through operations such as chromosome coding, fitness calculation, selection, crossover, and mutation. The dynamic allocation model and algorithm simulation are performed to compare the dynamic allocation and static fixed allocation methods. The simulation results show that the satellite communication task allocation algorithm based on GA algorithm can well satisfy the satellite communication task guarantees of different levels, and has certain reference value for improving the resource utilization of satellite communication systems.

Coexistence of satellite and terrestrial wireless communication systems in the same frequency band is quite promising for addressing the challenge of spectrum scarcity. To cope with the inevitable inter-system interference, radio resource allocation at both sides should be carefully re-optimized. In this paper, we focus on a scenario where a satellite communication system and a terrestrial distributed antenna system (DAS) coexist via spectrum sharing. We particularly utilize the radio map (RM) to reduce the system overhead for channel acquisition. Based on the large-scale channel state information at the transmitter (CSIT), which is derived from the RM, we propose an optimized power allocation scheme to improve the achievable sum rate of the terrestrial system. For the satellite side, an opportunistic user scheduling scheme is presented, to reduce the harmful leakage interference to the terrestrial mobile users. Simulation results demonstrate that the proposed RM-based coordination scheme can significantly promote the performance of satellite terrestrial coexistence, although the small-scale channel fading has been ignored in the formulated optimization.

This article is concerned with how to represent in system design the kinds of features of work settings as reported by ethnographic studies of work. Various researchers and practitioners have found that ethnomehodological analyses of work settings can provide useful insights to the work processes and settings in which system design is interested. Previously at Lancaster University, we examined ways in whisk ethnography can be used in h e design process and how the results of ethnographic analyses can be presented in such a way as to be useful components of the design process. This article reflects an effort to approach these methodological issues from a different perspective. It examines how the lessons learned from ethnographic studies can be reflected in the design process itself and in particular how standardized design artifacts (e.g., models, documents) can express the type of information that ethnographic studies produce. The article focuses on how ethnographic analyses can influence the main representational artifact in systems design—the model of the system being developed. We examine how the Unified Modeling Language for object-oriented design can be used to express information about awareness in cooperative systems.
