摘要
为了进一步提高Logistic-Map混沌序列的互相关性与自相关性,提出了一种改进型的Logistic-Map混沌序列的构造方法。通过Matlab仿真出扩频通信系统,并对改进型Logistic-Map混沌序列的相关性特性进行了分析,并与传统的Logistic-Map混沌序列做了比较。仿真结果表明,改进型Logistic-Map混沌序列与白噪声的统计特性一致,并且该混沌序列具有更为理想的互相关和自相关特性,更加适合作为扩频通信地址码。
In order to further improve mutual Logistic-Map chaotic sequence autocorrelation and correlation, this paper proposed a modified Logistic-Map chaos. By Matlab simulation from spread spectrum communication systems and improved Logistic-Map correlation characteristics of chaos are analysed, and unlike traditional Logistic-Map chaos has done a comparison. Simulation results show that improved Logistic-Map chaos and statistical properties of white noise, and the chaos has more ideal cross-correlation and autocorrelation, more suitable as a spread spectrum mailing code.
