MC-CDMA system evaluation using the MMSE decorrelator and the PIC in the reverse link over an asynchronous channel environment

We have evaluated the performance of the multi-carrier code division multiple access (MC-CDMA) system in an asynchronous channel environment transmitting in the reverse mode. The MMSE detector and the performance of a parallel interference canceller (PIC) scheme have been compared, assuming that users incoming at the base station are synchronous.
