Abstract :
We analyze the performance of code division multiple access (CDMA) systems with multicarrier (MC) that employ multiuser detection in asynchronous uplink frequency selective fading channels. We obtain the bit error rate (BER) performance of MC-CDMA in terms of the number of users, the spreading factor, the number of sub-carriers and frequency offset. The analytical and simulation results show that MC-CDMA with decorrelation detection displays the BER that varies with frequency offset as well as system loading
