MC-CDMA (Multi Carrier Code Division Multiple Access) plays an important role in modern wireless communications.Modern communication required an efficient spectrum usage and capacity and throughput.MC-CDMA provided the solution of these problems.MIMO refers to links with multiple antennas at the transmitter and receiver side.CDMA systems combined with multiple antennas is a promising technique, beyond 3G and 4G wireless communications.MIMO provides spatial diversity, which mitigates the fading.The usage of multiple antennas can significantly improve the performance of wireless communication system.This work also derives simulation through MATLAB of average bit error rate verses bit energy to noise ratio of multicarrier code division multiple access over Rayleigh channel using QPSK and BPSK modulation additive white Gaussian noise.
