摘要
本文讨论了混沌序列在直接序列扩频通信系统中的应用。针对简单混沌序列轨迹周期短以及存在误差传播现象,提出了一种改进的混沌扩频序列产生方法。并对混沌扩频序列的特性进行了分析和研究。
This paper discusses the application of chaotic sequences in DS/SS
communication systems. It proposes an improved method for generating chaotic spread spectrum
sequences, concerning the fact that the period of the trajectory of the simple chaotic sequences is
short and there is the error propagation. It also investigates the properties of the chaotic spread
spectrum sequences.
