摘    要:本文给出了码分多址混沌通信的一种同步和解调方法,其核心就是以混沌序列作为地址码,利用混沌序列优越的相关特性进行相关解调和同步。系统同步不需要发送专门的同步信号,直接利用所发射的载有信息的调制信号进行相关同步;改进的同步方法简单可靠,使系统同步时间减少50%;系统仿真实验证明了该方法的正确性和有效性。

关 键 词:DS-CDMA  码分多址  混沌通信  解调

Abstract:A method of correlation synchronization and demodulation for chaotic code-division multiple access systems is given. Its key is devoted to exploit chaotic signals as address codes and demodulated by excellent correlation characteristic of chaotic sequences. There is no any signals for synchronization in the system. Synchronization is reliable and easy to be implemented. The time on synchronization is reduced about 50% using improved way. The system has been designed that features robustness to channel white noise and multiple access interference. The correctness and validity of the method are demonstrated by a simulation example.
Keywords:correlation synchronization  DSCDMA  Chaotic sequences
