In this paper, a study of the differential chaos shift keying for discrete time implementations is proposed. Then we analysed the performance of this modulation system. A new approach is considered to compute an exact bit error rate expression. The idea of this approach is to compute the probability density function of the chaotic bit energy and to integrate the bit error rate over all possible values...
In this paper, an extension of the existing chaotic digital modulation named chaotic cyclic attractors shift keying (CCASK) is proposed, which uses different orders of chaotic cyclic attractors to modulate the information. The new scheme is analysed under a discrete-time domain, and the noise performance in AWGN channel is simulated, and also calculated in a mixed analytic-numerical way, under some...
