Abstract :
Recently, it has been studied how to reduce the probability of interception and to increase the efficient security in the wireless digital communication systems. Among the possible approaches for the information security, the chaotic signal can be used to encode information very efficiently in many ways due to the inherent characteristic of irregularity. In this paper, in noise and interference environment, we analyze BER performance depending on the selection of spreading factor. And we propose the selection condition of spreading factor for the maximize BER performance of chaotic CDSK modulation system. Through the theoretical and simulations, it is confirmed that Henon map is better than the other three systems when SF is 70.
