چکیده
Multi-carrier code division multiple access (MC-CDMA) is modulation method for high speed data communication. The usage of MIMO MCCDMA can significantly improve the performance of wireless communication system. This paper presents the analysis of Multi Input Multi Output MultiCarrier CDMA system performance for BPSK, QPSK, MSK modulation over AWGN channel and Rayleigh channel. This represents the performance analysis of MIMO MC-CDMA system when it has users 2, 4, 16, 32 and 64 users and 1T-1R,2T-2R,4T4R,NT-NR on AWGN and Rayleigh channel. The SNR between 0dB and 20dB the BER value showed an effect of AWGN and Rayleigh fading channel on the MIMO Multi-Carrier-CDMA system. It also compare MIMO Multi-Carrier-CDMA BER vs. SNR over BPSK,QPSK and MSK modulation techniques show that minimum BER obtained using NT-NR with MSK modulation technique for both AWGN and Rayleigh channel. Keywords—MC-CDMA,QPSK and MSK modulation, Rayleigh channel, AWGN, Walsh code and BER Performance.
