Performance evaluation of DCSK system with chaotic maps

In this paper, we analyze the performance in differential chaos shift keying (DCSK) schemes using different chaotic maps such as Gauss map, Tent map, Gingerbread man map, and Henon map. As technologies of communications develop, the need for data security is also significantly improved. DCSK modulation technique has advantages of traditional spread spectrum system and also provides enhanced data security. We ensure that the performance with Henon map is better than the other chaotic maps with typical spreading factors and at reasonable SNR levels.
