For mobile/personal satellite systems, an ARQ protocol with low transmitter/receiver complexity as well as high throughput performance in a long round trip delay (RTD) and even in a bad channel condition, is required. A new selective-repeat (SR) ARQ with multicopy retransmission is proposed and the performance on an AWGN channel is analyzed. The proposed scheme can viewed as a modified version for SR+Stutter (ST) Scheme 2. The basic idea of the strategy is to repeat only erroneous blocks stored in the /spl nu/N block transmitter buffer multiple times, when /spl nu/ consecutive retransmissions in SR mode is received in error, where N denotes the RTD in blocks. Numerical analysis in the case of N block transmitter/receiver buffer shows that the proposed scheme presents a better performance than the SR+ST scheme 2 of the 2N block transmitted receiver buffer, as the channel BER becomes higher.
