Abstract

This paper investigates the minimum mean square error (MMSE) parallel interference cancellation multiuser detection (MUD) schemes in uplink for code division multiple access (CDMA) based multiple input multiple output orthogonal frequency division multiplexing (MIMO-OFDM) system. The BER performances of three types of MMSE-PIC, zero forcing (ZF) and MMSE MUD schemes are compared. The simulation results show that the MMSE-PIC schemes are superior to the conventional ZF and MMSE schemes.
