Abstract: The performance of a multicarrier DS CDMA system is studied in the correlated fading channel.The formula of the diversity system BER is revised, and through system simulation and numerical calculation, a comparison is made between the performance of MC-DS-CDMA system and that of the single-carrier Rake system in the channel with an exponential power delay profile.

Key words: CDMA, multicarrier, correlated Rayleigh fading
