This paper analyzes the performance of DEC- Parallel Interference Canceling(DEC-PIC) multiuser detector exploited in MC-CDMA system. It is compared with Hara's Minimum Mean Square Error Combining(MMSEC) single-user detector in the uplink and downlink channels. The simulation results show that MMSEC single user detector is better in the downlink, and it can resist the channel estimation error. And in the uplink, the performance of the multiuser detector is better, but the large channel estimation error will bring performance degradation.
