Abstract :
An answer is provided to an interesting question: whether OFDM or multicode MC-CDMA can achieve better BER performance for the same data rate and the same bandwidth in a frequency selective fading channel. It is suggested by computer simulation that multicode MC-CDMA using MMSEC provides a superior performance to OFDM.
