| Abstract: | Aiming at the characteristic of MSS, the reason of signal attenuation by rain is analyzed and the calculation method of rainfall attenuation is given. Ka band is normally used for the business of mobile communications. Analysis result shows that the signal of this band gets rainfall influence greater. This paper puts forward several methods of rainfall attenuation compensation and gives the systematic principle figure of go up trip power control. |
