| Abstract: | This paper analyzes on the performance of Parallel Interference Cancellation(PIC) multi-user detection for downlink MC-CDMA system in the presence of channel estimation error,derives in detail the system bit error rate expression formula,and in contrast with the BER formula without channel estimation error,illustrates that channel estimation error reduces the system performance,and puts forward an effective method which can combat the channel estimation error. |
