摘要: 针对差分混沌移位键控(DCSK)传输率低这一缺点，以及为了进一步改善系统的误码性能，该文提出一种短参考正交多用户DCSK(SOM-DCSK)通信系统。该系统将参考信号缩短为每个信息承载信号的1/P，通过延迟时间的不同传输多个用户，然后在每个信息时隙中利用希尔伯特变换的正交性达到传输2 bit信息信号的目的。该文推导了SOM-DCSK系统在加性高斯白噪声(AWGN)和Rayleigh衰落信道下的比特误码率(BER)公式并进行了实验仿真。仿真结果表明：相同条件下，该方案相比于传统多用户系统的误码性能有了明显的改进，具有很好的实用价值。Abstract: Considering the shortcomings of Differential Chaos Shift Keying (DCSK) transmission rate and to further improve the system error performance, a Short reference Orthogonal Multiuser DCSK(SOM-DCSK) communication system is proposed. The system shortens the reference signal to 1/P of each information bearing signal, and transmits multiple users by different delay times. Then the orthogonality of Hilbert transform is used in each information slot to achieve the purpose of transmitting a two-bit information signal. The Bite Error Rate (BER) formula of SOM-DCSK system in Additive White Gaussian Noise (AWGN) and Rayleigh fading channel is derived and experimentally simulated. The simulation results show that BER of the scheme has obvious improvement compared with the traditional multi-user system under the same conditions, and it has good practical value.
