摘要
码分多址(CDMA)扩频通信系统的关键问题之一是如何选择优质的扩频码。文章采用Logistic映射方程产生混沌序列,对基于混沌序列的CDMA扩频通信系统进行仿真研究。结果表明,混沌序列具有生成简单,可用码组数目多、保密性能高等优点,可以很好地应用于扩频通信系统。
One of the key issues in Code Division Multiple Access(CDMA) system is how to select spreading sequences with good properties.A Logistic map based chaotic CDMA system is studied in this paper.The simulation results show that large number of chaotic sequences are easy to generate and are suitable to be used in spread spectrum communication system for the good security.
