Abstract

Spreading codes play an important role in multiple access capacity of DS-CDMA.M-sequences , has been traditionally used as spreading codes, they are generated by shift registers , they are periodic in nature and less in number so this limits the security. This paper present an investigation on use of chaotic sequences ;that recently ,chaos theory has developed a new area that is relevant to future radio spectrum management and security. one of the chaotic systems is used as a generator of sequences is non –linear recursive equation (logistic map).
