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,论文分析了混沌序列的伪噪声特性,介绍了实值混沌序列的量化方法,仿真了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,完全可以作为扩频码应用到现有的DSSS通信系统中。
For the purpose of applying digital chaotic sequences directly to the existing digital communication system, this paper analyzes the characteristics of pseudo noise of chaotic sequences, introduces the method of quantization of real chaotic sequences, and simulates the characteristics of digital chaotic sequences, including 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. It can be used as spread spectrum code in DSSS communication system.
