Abstract :
In order to restrain the interference of co-channel users in uplink STBC-OFDM system, the combined linear MMSE multiuser detection with interference cancellation is proposed in this paper. Theory analysis and simulation results reveal that the proposed schemes have a substantial performance improvement compared to the traditional detection scheme.
