Abstract :
A new communication scheme combining both MC modulation and DS-CDMA with a concatenated orthogonal/PN spreading scheme is proposed. This scheme incorporates the advantages of both DS-CDMA with a concatenated scheme, and an MC modulation technique to combat the effect of a multipath fading channel. It is shown that the proposed system outperforms the MC-CDMA system with a conventional PN sequence
