| 摘 要： | 利用相空间多次重构的混沌映射，为相干方式的混沌数字通信问题，提供一种解决方案。新映射产生的混沌码序列性能更加优异，自相关性明显改善，最大Lyapunov指数由0.697增加到5.545，复杂度也明显提高，仿真证实，利用新的混沌映射，系统抗多址性能提高；基于新映射混沌码良好的相关性能和抗多址性能，设计了一种滑膜相关峰检测同步法，完成离散混沌系统同步，实现相干方式混沌数字通信。

| Abstract: | Aiming at the problems in coherent chaotic digital communication. Using the phase space multiple reconstracted map, a solution is provided. The performances of chaotic codes generated by new map are better then before. The correlation and the complexity are all improved. And the maximum Lyapunov exponent increases from 0.697 to 5.545. Calculation and simulation show that with the new chaotic map, capability of anti-multiple access interfer is promoted. Basing on the outstanding correlation performance and the good anti-multiple access capability of this new chaotic codes, the sliding mode correlation peaks detection method is suggested, to achieve synchronization of two discrete chaotic systems. The coherent chaotic digital communication system is achieved eventually. |
