Multi Carrier Code Division Multiple Access (MC-CDMA), a promising technology for the 4G communication systems is considered in this paper. The foremost limitation of such system is the Multiple Access Interference (MAI) which is due to frequency-selective fading, near-far effect, frequency offset, and nonlinear power amplification due to clipping noise. The performance of MC-CDMA under such scenario is poor and optimal detection is one of the solutions with a high complexity is required. In this paper the Bit Error Rate (BER) performance is compared under clipping noise with sphere decoding and Global search algorithm based Multiuser detectors
