Abstract :
Results on quaternary complex sequences have provided quaternary sequences that have better periodic correlation properties than binary sequences. In this paper we examine a receiver architecture that takes advantage of the superior periodic correlation properties of these quaternary sequences, and we investigate the aperiodic correlation properties that permit quaternary direct-sequence spread spectrum to discriminate against multipath and provide multiple-access capability for asynchronous transmissions
