Abstract

Abstract

In order to meet the demand of modern communication, multiuser access technology is an important development trend of current chaotic communication. To improve the Bit Error Rate (BER) performance of the existing multiuser chaotic communication schemes, a MultiUser communication scheme based on Segment Shift Differential Chaos Shift Keying (MU-SSDCSK) is proposed. According to the users number in transmission, the reference signal of MU-SSDCSK is divided intom segments, which are then shifted and matched with different Walsh codes that therefore can make the information-bearing signals orthogonal to each other. The theoretical BER formula of this new scheme is derived in Additive White Gaussian Noise (AWGN) channel. The simulation results show that the proposed scheme can effectively improve BER performance, and has certain application prospect in the chaotic communication field.
