基于一种Logistic映射的混沌跳频序列

Chaotic FH Sequences Based on a Kind of Logistic Map

基于Ｌｏｇｉｓｔｉｃ映射，提出了产生混沌跳频序列的方法。分析了该混沌跳频序列对初始条件的敏感依赖性和相关性，然后进行了数值模拟，并对该方法所产生序列的相关性与其他方法进行了比较。实验结果表明，用该方法产生的混沌跳频序列具有更好的相关性，它适用于跳频多址通信。

Based on a kind of Logistic map, a method to generate chaotic frequency hopping (FH) sequences is proposed. Sensitive dependence of the sequences on the initi al condition and the Hamming correlation of the sequences are analyzed and computer-simulated. The correlation of the sequences is compared with those of others . Experimental results show that the chaotic FH sequences generated with the proposed method possess more excellent correlation properties.
