Open publisher page 0 citations

Abstract

In this paper, we propose a new communication scheme combining both MT modulation and DS-CDMA with a concatenated orthogonal / PN spreading sequence. This scheme incorporates the advantages of both DS-CDMA with a concatenated sequence, and an MT modulation technique to combat the effect of a multipath fading channel. It is shown that the proposed system ourperforms the MT-CDMA system with a conventional PN sequence.
