Modeling of rain attenuation using equiprobability of rain fade and rain fall

Proposed work shows the modeling of rain attenuation. This modeling is based on rain rate versus rain attenuation characteristics by using equiprobability. Total three years data of signal and rain is used in this work. Data includes the information of received signal strength from IPSTAR satellite and rain fall data. Two year signal data at 20.2 GHz and two year rain data of corresponding period is used to develop rain attenuation model and one year data is used for validation. Delhi earth station data provided by SAC, Ahmedabad is used. The outcome of this work is very useful in short term signal behavior and rain fade mitigation technique to support uplink power control.
