This paper presents high-spread (HS) random interleavers based interleave-division multiple access (IDMA) scheme. High-spread feature of a randodecm interleaver offers high-spread characteristics to interleavers and thus produces extrinsic values with low correlation. As interleavers are key components for user separation in the IDMA, the HS interleavers are employed in the IDMA for performance improvement. In addition, by replacing random interleavers with the HS interleavers in the IDMA, bandwidth efficiency is achieved by means of reducing the length of the repetition code. Performance evaluation shows that the proposed scheme of the IDMA with the HS interleavers provides significant BER performance improvement and moderate increase in bandwidth efficiency.
