| 摘 要： | 提出了一种新的变换域通信系统基函数生成方法——Logistic数字混沌映射法，并对基于Logistic混沌序列基函数的特性进行仿真，同时将其与基于m序列的基函数进行对比分析。仿真结果表明，基于Logistic混沌序列基函数具有较好的伪随机特性、多址特性，且函数数量巨大。

| Abstract: | A new method using digital chaotic mapping to generate the basis function is proposed in this paper. The analysis and the stimulation of logistic chaotic mapping is presented. Compared with the method of rn random sequences, the implementation of the logistic chaotic has a good pseudorandom and multi access performance and it can produce a large of functions. |
