Abstract

A SISO iterative joint detection and decoding receiver structure is proposed in an uplink turbo-coded multiple-input multiple-output (MIMO) multicarrier code division multiple access (MC-CDMA) system. The SISO detector is achieved by using soft interference cancellation V-BLAST detection and multiuser detection with minimum mean square error (MMSE) technique. And the soft interference cancellation is composed of the canceling of multiple-access interference and co-antenna interference (CAI). Simulation results show that the iterative cancellation receiver in turbo coded system can gain much better performance than conventional receiver in uncoded system. A low-complexity scheme is also presented.
