摘    要:为了提高现有单频干扰下BPSK接收性能恶化分析方法的准确性和实用性,本文引入干扰信号相位作为随机变量,得出了新的分析方法.该方法首次准确量化了单频干扰下BPSK接收性能的恶化程度,普遍适用于BPSK调制体制下的卫星通信系统.给出了MATLAB数值仿真和现场实测结果.将其应用到探月工程嫦娥一号(CE-1)任务中,对CE-1通信系统受日本SELENE月球探测器信号干扰进行了准确的定量分析,为地面接收站的抗干扰设计以及中日双方探测器频率协调工作提供了依据.

Abstract:The performance degradation in the presence of monofrequency interference on BPSK communication systems is analyzed in this paper.In particular,a new method more accurate and applicable than the methods presented before is derived here,by assuming the jamming phase as a uniformly distributed random variable.MATLAB simulations and measurements in the ground station of CE-1(Chang'E lunar mission of China) are carried out.The results are in good agreement with our theoretical results,showing that the approach ...
