| 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. |
