Abstract

A novel CDMA based multiple-access scheme for differential chaos shift keying (DCSK) is proposed in this paper. By using the orthogonal pseudo-random codes, multi-user access ability can be provided for both synchronized and asynchronous multi-user DCSK system. Firstly, the transmitter and receiver structure of CDMA-DCSK system are given, which are with slight modification to the original DCSK system, and the basic idea and principle are also described. Then the bit error rate performance of the proposed CDMA-DCSK scheme is analyzed, and several formulae for evaluating BER are obtained. Finally, some simulation results, comparison, and discussions are presented.
