摘要

混沌作为一种非线性动态系统中的现象，受到了人们的重视，研究工作者纷纷探索它在通信中的可能应用．本文分析了一种广泛研究的离散时间动态系统Ｌｏｇｉｓｔｉｃ－Ｍａｐ所产生的混沌序列的白噪声统计特性．为适应实际需要还给出了Ｌｏｇｉｓｔｉｃ－Ｍａｐ简便的数字硬件实现方法．据此，进一步提出数字混沌序列的概念，研究了数字混沌序列在ＣＤＭＡＤＳ／ＳＳ通信系统中的具体应用．仿真数据显示Ｌｏｇｉｓｔｉｃ－Ｍａｐ数字混沌序列拥有较理想的自相关和互相关特性，且数目极大，适合作为扩频地址码．

Abstract

As a phenomenon found in non-linear dynamic system

Chaos has been paid attention to. Researchers are looking for its possible application in communication. This paper analyzes the statistic characteristic of chaotic sequences generated by a widely studied discretetime dynamic system

Logistic-Map. We find that their statistic characteristics is identical with those of white noise. We also propose a digital hardware implementation for Logistic-Map and the conception of digital chaotic sequence. The simulation results show that Logistic-Map digital chaotic sequences have good correlation property and their number is large

suitable for acting as spread-spectrum address sequences.
