MC-CDMA System for Multi-User Using Walsh Code on Rayleigh Fading Channel

The aim of this paper is to investigate the BER and SNR analysis of multiuser Multi Carrier Code Division Multiple Access(MC-CDMA) system where a new combination of different fading channels is used. Walsh code has been chosen for spreading code and AWGN and Rayleigh channels are used for fading channels. In this paper 64,128,256,512 and 1024 users are used. The SNR range is 0 to 20db and the BER value showed an effect of AWGN and Rayleigh fading channel on the MCCDMA system.
