摘要：
A performance analysis of multiuser detectors over a fading channel with the presence of carrier frequency offset in MC-CDMA system 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. On the uplink transmission, the performance of the desired user is not affected by the amount of frequency offset experienced by other users in the system. Based on the performance evaluation, multiuser detectors can tolerate only a small amount of frequency offset.
