摘要：
In this paper, an iterative multiuser receiver for convolutionally coded direct sequence-code division multiple access (DS-CDMA) system is proposed. The proposed receiver consists of a soft-in/soft-out (SISO) decision-feedback multiuser detector and a bank of single-user SISO channel decoders. At each iteration, extrinsic information are extracted from the multiuser detector and the channel decoders, and are then used as the prior information in the next iteration. Computer simulations have shown that the proposed receiver offers performance close to single-user bound for weak user in near-far effect.
