Performance of M-ary DPSK Communication Systems Employing Differential Phase Detection on Rayleigh Fading Channels

本文提出一种适合于瑞利衰落信道多进制差分相移键控系统相位比较解调的性能分析方法，推导出符号错误率解析表示式，考虑了瑞利衰落、时间选择性衰落和高斯白噪声对体制性能的影响，并针对衰落功率谱为高斯型和矩形分别对二进制。

This paper presents a method for determining the error probability of MDPSK communication systems with differential phase detection on Rayleigh fading channel,and the analytic expression of symbol error rate is derived.The effects of Rayleigh fading,time-selective fading and white noise on the performance of MDPSK systems have been considered.When the form of fading spectrum is assumed to be Gaussian or rectangular,the symbol error rate of BDPSK,QDPSK and ODPSK systems has been numerical calculated,respectively.
