产生伪随机序列的一种方法

由于混沌是一种动态的、类随机的非线性系统,且具有对初始条件敏感、连续的功率谱、各态遍历等特性,因此可产生伪随机序列。本文就是将混沌连续的功率谱进行反褶、平移、相加、缩放等变换构造出了一种新的伪随机序列,通过理论分析和仿真试验,初步验证了该序列的各项特性是满足了Golomb的3个公设。此序列产生方法简单,基本可以广泛应用于保密通信等领域。

A Method to Generate Pseudo-Random Sequence

Chaos is a dynamic and species-random and nonlinear system,and it has sensitive initial conditions,continuous power spectrum and traversal,so it is often used to generate pseudo-random sequence.This article makes use of the chaotic power spectrum deconvolution,adder,translational,zoom to construct a new pseudo-random sequence.Through theoretical analysis and simulation experiments,the characteristics of the sequence are able to meet Golomb's three public supposals.This method for sequence is simple,which can be widely applied in the field of secure communication.
