摘　　要：本文从截断混沌序列的相关特性入手 ,直接推导出混沌序列为地址码的异步DS CDMA通信系统的相关解调结果 ,仿真研究不同的混沌序列在异步DS CDMA条件下的多址特性 。With the correlation of truncated chaotic sequences,the correlated demodulation for asynchronous DS CDMA system in chaotic sequence is derived in the paper.It is shown that the system has multiple access and is robust by the theoretical analysis and computer simulations.Finally an optimization method of the chaotic spreading sequences is proposed.
