Abstract

In this paper, performance of different MultiUser Detection (MUD) receivers are investigated for a MultiCarrier (MC)-Code Division Multiple Access (CDMA) system in an Indoor Wireless Local Area Network (WLAN). Simulation results show that benefits of MC-CDMA schemes in terms of capacity, throughput and Bit Error Rate (BER), are enhanced by means of Least Mean Square Error (LMSE) and Selective Parallel Interference Cancellation (S-PIC) receivers, at the expense of a moderate increase in overall system complexity. In particular, the S-PIC receiver is able to outperform other techniques in all the conditions examined. Moreover, we have investigated robustness of our proposed scheme with respect to phase and/or amplitude estimates errors, to prove that performance are not highly affected if errors are not large enough.
