【 摘 要 】

The bit error rate of an asynchronous multicarrier code division multiple-access system in an additive white Gaussian noise channel is evaluated using Maximum Ratio combining and Automatic gain control methods.The usage of MC-CDMA can significantly improve the performance of wireless communication system. This paper presents the simulation of MC-CDMA system performance with BPSK modulation over AWGN channel and Rayleigh channel. It also represents the BER performance of MC-CDMA system when it has users 2, 4,16,32,64 for both AWGN and Rayleigh channel.
