Improved rain attenuation reduction factors for tropical region

摘要

The maximum utilization of radio spectrum is a major concern of global radio communication community. In the microwave region, rain is the significant cause of signal impairment in form of attenuation. An improved model for prediction of rain attenuation on earth to satellite path is derived using both radar and beacon data obtained from tropical region. The proposed model shows a considerable reduction in prediction error in term of standard deviation and Root Mean Square (RMS) error.
