摘　　要：直接序列扩频通信通常选择m序列和gold码作为地址码,但对于并行组合扩频系统其地址码数量少。在分析并行组合扩频系统基础上,研究Logistic-Map混沌扩频序列优选准则。Logistic-Map混沌扩频序列应用在并行组合扩频系统中,仿真结果表明,Logistic-Map混沌扩频序列可以提供数量众多的适于并行组合扩频通信系统的扩频序列族。DSSS usually takes m sequences or gold codes as address codes ,but the parallel combinatory spread spectrum （PC- SS） communication has small amount of them. This paper is devoted to the method of the optimize for Logistic - Map chaotic spreading sequences based on the model of the PC - SS communication. Logistic - Map chaotic spreading sequences have application to the PC - SS communication, and the result of simulation shows that Logistic - Map chaotic spreading sequences is fit to PC - SS communication for more sequences.
