Abstract

The article develops a methodology for analyzing the noise immunity of satellite communication systems under small-scale disturbances of the ionosphere, taking into account the possibility of general and time-selective fading of received signals Differential Phase Shift Keying. The refined dependences of the intervals of time and space correlation of fading in the transionospheric radio channel on the parameters of transmitted signals and the state of the ionosphere are obtained. The analytical dependence of the probability of erroneous reception of signals with Differential Phase Shift Keying on the average signal-to-noise ratio at the receiver input, the frequency-time parameters of the signals and the characteristics of small-scale ionospheric inhomogeneities was obtained.

卫星通信在小尺度电离层干扰和接收信号时选择性衰落下的抗扰性分析

本文提出了一种分析卫星通信系统在电离层小尺度干扰下的抗扰性的方法，该方法考虑了接收信号的一般衰落和时间选择性衰落的可能性。得到了跨层无线电信道衰落的时空相关间隔与发射信号参数和电离层状态的精细关系。得到了差分相移键控信号错误接收概率与接收机输入端的平均信噪比、信号的频时参数和小尺度电离层非均匀性特征的解析依赖关系。
