• A receiver structure, which has linear computational complexity with the number of users, is proposed for decoding multiuser information data in a convolutionally coded asynchronous DS-CDMA system in multipath fading channels. The proposed receiver architecture consists of a multiuser likelihood calculator followed by a bank of soft-input soft-output (SISO) channel decoders. Information is fed back from SISO channel decoders to multiuser likelihood calculator, and the processing proceeds in an iterative fashion analogous to the decoding of turbo codes. A simplification to the above receiver structure is given too. Simulation results demonstrate that for both receiver structures at high signal-to-noise ratios (SNR) both multiple-access interference (MAI) and inter-symbol interference (ISI) are efficiently suppressed, and single-user performance is approached. Furthermore, the proposed iterative receiver is near-far resistant.
