摘要

本文研究利用ｍ序列的扰动来实现有限精度混沌系统的方法．考察了扰动序列的周期、幅度以及扰动分布对混沌信号特性的影响．研究表明，扰动ｍ序列所需的阶数取决于混沌序列所需要达到的周期长度，扰动的位数取决于混沌映射的最大斜率．随着混沌系统实现精度的提高，所需的扰动幅度呈指数减小．

Abstract

This paper presents an approach to realize finite precision chaotic systems via perturbation of m-sequences. Several properties of the chaotic signal are studied under different perturbation parameters （i. e. period

amplitude and distribution）. It is shown that the order of m-sequence is determined by the period of the desired chaotic signal

and the perturbation bit number can be calculated from the maximal differential of the chaotic system. When the precision increases

the perturbation amplitude decreases exponentially.
