In a satellite communication system, the satellite or ground station can receive numerous external noise signals along with the main radio signals, which further generates a considerable impact on the quality of satellite communication. In particular, the external noise signals tend to be much larger than the interferences in the receiver owing to the usage of a low-noise amplifier, and thus we must consider the influence of the various external noises when designing the communication links of an earth-space satellite. Furthermore, the ground station of the satellite interferes with the ground service system on the same frequency. In system design, the coexistence analysis must be explored to define the coordination distance from the ground station. When defining such distance, it is imperative to consider the interference caused by beyond-line-of-sight (BLOS) propagation of rainfall satellite and atmospheric duct, in addition to the line-of-sight propagation of the interference signal.
