The system capacity and performance of MC-CDMA communication systems can be significantly enhanced by jointly employing MAP-based multiuser detection (MUD) and channel decoding techniques. In this paper, a group oriented soft iterative MUD based on the combination of smart antennas and iterative MAP-based MUD is presented. The proposed method is featured as a novel technique for further increasing the system capacity and performance. It is demonstrated that the performance of the proposed algorithm with low complexity can approach that of a signal user coded MC-CDMA system with an antenna array in AWGN and frequency selective fading channels.
