A New Structure of Chaotic Secure Communication in Wireless AWGN Channel

Abstract

Wireless technologies have become popular in recent years and usually applied in multimedia broadcasting, environment monitoring, mobile communication, etc.. In all applications, keeping information accuracy is very important. In this paper, to improve the security and accuracy of transmitted information, we proposed a new wireless communication structure based on three coupled chaotic systems. The performances, including SNR and BER in the AWGN channel, are verified and analyzed with MATLAB toolbox.
