Error performance analysis of coherent DCSK chaotic digital communication systems

An approach to calculating the approximate bit error rates for coherent DCSK in an AWGN channel is presented. By using logistic as the chaos generator and assuming ideal synchronization at the receiver, the BER of coherent DCSK in an AWGN channel is derived. The theoretical noise performance of coherent DCSK is again derived and is equal to that of coherent FSK. By computing and simulating, the theoretical BERs agree well with the simulated results.
