Owing to the fine anti-jamming ability of multi-carriers CDMA system,it has been established for one of the key technologies of the third generation mobile communication.The MC-CDMA system is extremely sensitive to the synchronization errors,which includs carrier synchronization errors.Many literatures had analyzed the carrier frequency offset performance of the MC-CDMA system,but they mainly based on the Rayleigh fading channel.By researching on the performance of MC-CDMA system carrier frequency offset in the Nakagami-mdistribution fading channel,the bit error ratio(BER) formulae about two kinds of detection technoloies,ieequal gain combing(EGC) and maximal-ratio combining(MRC)were given.The simulation under the Matlab environment indicate that the MC-CDMA system is extremely sensitive to the frequency offset.
