摘要：
The major drawback of Short Reference Differential Chaos Shift Keying (SR-DCSK) system is the low data transmission rate. To solve the problem, a Short Reference Multi-User Differential Chaos Shift Keying (SR-MUDCSK) communication scheme is proposed. The orthogonality of Walsh code is used to transmit the information of multiple users, which effectively improves the data transmission rate. The theoretical Bit Error Rate (BER) performance is analyzed, and experimental simulation is carried out under AWGN and multipath Rayleigh fading channel environment, respectively. The results show that the system has a significant improvement in transmission rate, and the energy efficiency is also significantly improved. Therefore, it is of great value in application.
