软件无线电Rossler超混沌语音保密通信系统

Communication System of Speech Secure with Rossler’s Hyperchaos Based on Software Radio

本文以软件无线电为操作平台 ,研究了Rossler超混沌动力学方程以及超混沌语音保密通信系统。采用Rossler时间连续方程产生超混沌 ,调制到软件无线电中 ,形成一套基于软件无线电的超混沌语音保密系统。运用计算机进行语音仿真实验。文中对超混沌密钥信号的产生与通信作用原理进行讨论 。

Communication System of Speech Secure with Hyperchaos and Rossler’s equation of hyperchaotic dynamics is researched and it is based on Software Radio in this paper. Used the time serial function for Rossler and the equation for time continuity to produce hyperchaotic state and modulate in to the software radio to form a set of the Communication System of Speech Secure with hyperchaos. Emulation of speech secure communication the system was tested by the computer. About hyperchaotic signal produce principle and their reciprocity effect were discussed in this paper, too. Its security characteristic was analyzed from theory in the software radio system.
