The book presents MC-CDMA system for future generation wireless communication system. The analysis is done to evaluate the BER versus SNR ratio in a MC-CDMA wireless system over Rician and Rayleigh fading channels. Finally the system is assessed by using two users whose data is amalgamated as a mixed signal over the AWGN channel and the BER and other parameters are evaluated. The coding schemes used are Walsh Hadamard code, Gold code and STTC code.
