| 摘 要： | 离散混沌动力系统Logistic-Map产生的混沌离散序列具有良好的统计特性和对初值非常敏感的特性，利用这些特性，提出一种基于Logistic-Map的数字混沌调制方法，并构造相应的保密通信系统，且进行了计算机仿真，在此基础上提出了调制系数宽范围变化的数字泥沌调制方法。

| Abstract: | Chaotic discrete sequences produced by Logistic-Map have very good statistic properties and are sensitive to first values. Based on Logistic-Map, a kind of digital chaotic modulation method is given. Then corresponding secure communication system is simulated in computer. It provides an access to put forward another modulation method in which modulation correlation can vary widely. |
