摘要
本文从混沌序列具有的伪随机特性入手,利用蔡氏电路建立了一个混沌序列发生器,实验统计分析证明可以利用蔡氏电路产生一种较理想的混沌伪随机序列;通过对以混沌伪随机序列为基础得到的混沌扩频序列的特性分析,表明基于蔡氏电路的混沌扩频序列适合于扩频通信中的应用。
Proceeding with pseudo-random characteristic of chaotic sequences, a chaotic sequences generator has been fabricated using Chua's circuit, and from the experimental statistical analysis it has also proved that we can use Chua's circuit to produce a much reasonable pseudo-random sequences. By analyzing the characteristic of chaotic spreading sequences based on chaotic pseudo-random sequences in detail, it has shown that this spreading sequences is useful for applying spread-spectrum communication.
