In this paper we propose a new Wide band Multicarrier (W-MC) Code Division Multiple Access (CDMA) scheme that delivers a great immunity against multi-user interference (MUI) caused by interferers in the system and from which the classical MC-CDMA suffers considerably. For the synchronous-case, the results show that the new system performance was comparable to a single-user system. This exceeds enormously the performances obtained for MC-CDMA. The asynchronous Wide Band MC-CDMA scheme is also analyzed and the performances are always best. This is reflected by the Bit error rate (BER) of the systems with either equal-gain combining (EGC) and maximum-ratio Combining (MRC) equalization techniques.
