Applying MIMO technique to conventional MC\DS CDMA scheme to form MIMO MC\DS CDMA system will improve the system performance.A parallel interference cancellation QR decomposition detection algorithm of MIMO MC\DS CDMA system is proposed based on the study of low complexity algorithms with QR decomposition,in which error propagation is further suppressed.Simulation results have shown that the proposed algorithm improves the BER performance significantly in single user or multi-user environment.
