摘　　要：为了将数字混沌序列直接应用到现有的数字通信系统中,分析了混沌序列的伪噪声特性,介绍实值混沌序列的量化方法,仿真数字混沌序列的性能,最后对基于数字混沌序列的DSSS通信系统进行了仿真。结果表明,数字混沌序列具有良好的自相关和互相关特性,将其应用到DSSS通信系统中可以解决当前存在的系统间相互干扰及多址干扰等问题。For applying digital chaotic sequences directly to the existing digital communication system, this text analyzes the characteristics of pseudo noise of chaotic sequences,introduces the method of quantization of real chaotic sequences, simulats the characteristics of digital chaotic sequences,and simulats the DSSS communication system based on digital chaotic sequences. The results indicate that digital chaotic sequences have good characteristics of auto - correlation and cross - correlation. Applying it to DSSS communication system can resolve the existing problems of the interference among systems,and the multi - address interference.
