ABSTRACT:
A multicarrier direct sequence spread spectrum system and method. A maximal combiner is employed at the receiver for maximizing signal-to-noise ratio out of the receiver. The multicarrier system provides robustness against multipath fading, and narrowband interference suppression. The multicarrier system is suitable for a CDMA overlay scheme for PCN.
