摘　　要：将时空混沌序列应用于 DS CDMA系统 ,给出了系统同步模型 ,并对系统性能进行了分析。结果表明 :用混沌序列作为地址码的 CDMA系统 ,可以有效地抑制干扰的影响 ,并能提高系统的传输效率 ,对First,the model of DSCDMA communication system based on spatiotemporal chaotic sequences is proposed,then the model of system synchronization is given,and the system performances,including antijamming,MAI and communication efficiency are discussed.The computer simulation results show that the performances of the chaotic CDMA communication system are much better than traditional one,and the chaotic spreading sequences have great influences in performance improvement of CDMA system.
