A Multiple Access Technique for Differential Chaos Shift Keying

Free registration required

Executive Summary

Various chaos-based digital communications techniques have been proposed recently. Among them, Differential Chaos Shift Keying (DCSK) allows the receiving end to decode factors. In this paper the authors also use AWGN channel and see how it effects the BER, the signal using non coherent detection. This paper proposes and analyses a multiple access scheme for DCSK. A simple 1-dimensional iterative map has been used to generate the chaotic signals for all users. Bit error probabilities have been derived numerically for different number of users and computer simulations have been performed to verify the results and also compare the BEP for different spreading factors.
