摘要
本文提出了一种基于混沌映射的扩频序列产生方法,运用混沌的遍历理论分析了理想情况下混沌扩频序列的性能,实际性能作了计算机模拟.初步结果显示,混沌扩频序列是直接序列扩频通信的优选序列.
A new spreadign sequences generator based on a class of chaotic maps is proposed.The theoretical performance of these sequences are shown to be ideal by using the ergodic theory of chaos. Real performance are then investigated by computer simulation. The preliminary results show that chaotic spreading sequence are good candidates for direct-sequence spred -spectrum communications.
