Abstract :
In this paper, the 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.
