摘要: In this paper, the mutual information transfer characteristics of several novel turbo multiuser detectors (MUD) employed in space division multiple access (SDMA) aided orthogonal frequency multiplexing (OFDM) systems are investigated with extrinsic (EXIT) charts. These schemes Bayesian, Soft Interference cancellation minimum bit error rate (SIC-MBER) and reduced-complexity Bit Error Rate (RMBER) MUDs. order to increase effective throughput system, a powerful MUD has be so- called "rank-deficient" scenario, namely when number transmit antennas exceeds that receiver antennas. The classic mean square (MMSE) solutions exhibit low complexity. However, they overwhelmed rank-deficient scenarios. these situations non-linear MUDs required, which designed treatise.
