摘要
设计了一种混沌扩频码,在该扩频码的生成过程中引进了收缩密钥流生成器的方法,其特点是在较低的实现精度下能得到周期极大的扩频码,且具有良好的相关特性,克服了混沌实际实现时所遇到的有限字长效应问题。
We design a chaotic spread code, which introduces the method of shrinking key-stream generator. Its characteristics are that the period of sequence is very large with a lower precision and the correlation propertyis good. This method overcomes the problem of finite precision effect when we implement chaotic system practically.
