噪声环境下离散混沌信号的复用

Multiplexing of discrete chaotic signals in presence of noise

Nithin Nagaraj, Prabhakar G. Vaidya

摘要:

本文研究了噪声环境下离散混沌信号的复用问题。现有的方法都是基于混沌同步的,但这种同步方法易受噪声和参数失配的影响。此外,这些方法不能复用两个以上的离散混沌信号。提出了两种基于符号序列不变性原理和有限精度实现任意长混沌映射符号序列初始条件的多离散混沌信号复用方法.

英文摘要:

In this paper, multiplexing of discrete chaotic signals in the presence of noise is investigated. Existing methods are based on chaotic synchronization which is susceptible to noise and parameter mismatch. Furthermore, these methods fail for multiplexing more than two discrete chaotic signals. We propose two novel methods to multiplex multiple discrete chaotic signals based on the principle of symbolic sequence invariance in the presence of noise and finite precision implementation of finding the initial condition of an arbitrarily long symbolic sequence of a chaotic map.
