摘要
本文介绍了一种新的扩频序列产生方法,利用蔡氏混沌电路作为驱动序列,对时空混沌模型单向耦合映象格子进行驱动产生扩频序列,验证了这种扩频序列良好的自相关、互相关特性,结果表明,本方法产生出来的序列扩频特性,性能良好,适用于扩频通信系统。
A novel generation method of s pread-spectrum sequences based on spatiotemporal chaotic model-OCML driven by Chua's circuit has been introduced in this paper. The good features of autocorre lation and crosscorrelation of this sequence are also testified. The simulation result shows that it has good spread-spectrum properties and meets the demand o f spread-spectrum sequence in the spread-spectrum communication systems.
