摘要/Abstract

摘要： 针对差分混沌键控(Differential Chaos Shift Keying, DCSK)误码性能较差，传输率低的问题，提出一种基于时间反转的多用户DCSK(Time Reverse Multiuser-DCSK, TRM-DCSK)通信系统.该系统利用时间延迟的不同来区分不同的信息时隙，在每个信息时隙中利用时间反转可以传输2bit的信息信号，然后将这2bit的信息信号叠加后作为信息承载信号一起发送.使用时间反转能增强信号之间的自相关性，改善了系统的误码性能.推导了TRM-DCSK系统在加性高斯白噪声(Additive White Gaussian Noise, AWGN)和Rayleigh衰落信道下的误码率公式并进行了实验仿真.仿真结果表明：在传输相同用户数的情况下，TRM-DCSK系统的误码性能相对于传统的多用户DCSK系统有了明显的提高.

Abstract: Aiming at the problem of poor bit error performance and low transmission rate of differential chaos shift keying (DCSK), the time reverse multiuser-DCSK (TRM-DCSK) communication system is proposed. The system uses different time delays to distinguish different information time slots. In each information time slot, two-bit information signals can be transmitted by time inversion, and then the information signals of the two bits are superimposed and transmitted together as an information bearing signal. The use of time reversal can enhance the autocorrelation of chaotic signals and improve the error performance of the system. The bit error rate formula of TRM-DCSK system in additive white gaussian noise (AWGN) and Rayleigh fading channel is derived and simulated. The simulation results show that the TRM-DCSK system is significantly improved compared with the traditional multiuser DCSK system when transmitting the same number of users.
