The Performance Analysis of DEC-PIC Detector Exploited in MC-CDMA System
MC-CDMA系统采用解相关-并行干扰抵消检测器的性能分析

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.
