Abstract: An efficient multiple user access over the wireless channel necessitates a communication system design that can overcome the adverse impact of multipath propagation such as Inter Symbol Interference (ISI) and Multiple Access Interference (MAI). This being the objective, a Multi Carrier Code Division Multiple Access (MC-CDMA) communication system is considered in this paper. MC-CDMA, being a combination of DS-CDMA and OFDM converts a frequency selective fading channel into multiple flat fading channels thereby mitigating ISI. To overcome the effect of MAI, Multi User Detection (MUD) based receiver is addressed. The performances of Blind successive Interference Cancellation (BIC) techniques are compared with Matched filter receiver and BMMSE receiver by simulating the entire system. The BIC is a multi-user detection technique that uses knowledge of only the desired user's signature sequence and his timing to estimate his information. This is done by executing interfe!
rence cancellation in a successive manner, starting from the most dominant component and successively canceling the weaker ones. Simulation results show that BIC scheme outperforms conventional MF receiver and BMMSE receiver.
Keywords: Inter symbol interference, Multiple Access interference, Multi user detection, Single user lower bound, Maximum mean energy.
