%X The code-shifted differential chaos shift keying(CS-DCSK)is an improved scheme of DCSK, which eliminates the delay circuits in receiver. It simplifies the implementation of system. For the study of the performance of CS-DCSK over the generalization multipath fading channels, based on Gaussian approximation(GA)the BER performance is analyzed over Nakagami-m fading channel. The expression of bit error rate(BER)is presented. Simulation results and numerical results show that the analyzed results are well consistent with the simulation results. And the BERs of different channel parameter m are compared and the reasons are analyzed.
