BER Performance of MC-CDMA Using Walsh Code with MSK Modulation on AWGN and Rayleigh Channel
Journal Title: INTERNATIONAL JOURNAL OF ENGINEERING TRENDS AND TECHNOLOGY - Year 2013, Vol 4, Issue 7
Abstract
Multi-carrier code division multiple access (MCCDMA) is method for high speed data rate communication. It skip the problem of inter symbol interference.MC-CDMA too provide spatial diversity, which mitigate the fading. 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 MSK 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 and 64 for both AWGN and Rayleigh channel. The SNR value between 0dB and 20dB the BER value showed an effect of AWGN and Rayleigh fading channel on the MCCDMA system. Also the comparison of MC-CDMA BER performance over MSK modulation and BPSK modulation techniques show that minimum BER obtained with MSK modulation technique for both AWGN and Rayleigh channel.
