A performance analysis of multiuser detectors for MC-CDMA over a fading channel in the presence of carrier frequency offset is presented in this paper. A theoretical analysis of the bit error probability of the detectors is derived. The theoretical analysis shows a close agreement to simulation results for a low value of the frequency offset and a high number of subcarriers. Based on the performance evaluation, multiuser detectors can tolerate only a small amount of frequency offset.
