Performance Analysis of Fractional Order DCSK Secure Communication System

摘要：

The research of chaos theory and its application in communication is the frontier of science and engineering,which provides a novel research field for conventional communication theory and also presents a broad application platform for nonlinear science.The fractional order chaotic system which had higher confidentiality than integral system was applied to physics and engineering are just a recent subject of interest. The use of fractional order chaos in differential Chaos shift keying(DCSK) has led to better secure performance,antiinterference ability12.The performance of DCSK communication system based on fractional order chaos (in this paper we call it FO-DCSK) is characterized in terms of bit error rate (BER) versus the signal to noise rate (SNR) by theoretic analysis and Matlab numerical simulation.The results of simulation show the superiority of this technique.
