PREDICTION OF RAIN ATTENUATION SERIES WITH DISCRETIZED SPECTRAL MODEL

The rain attenuation plays a major role in the design of satellite-to-earth links operating at high frequencies such as Ka band and Ku band. The signal suffers from a strong attenuation during the propagation path as raindrops absorb and scatter radio waves, which results in an increase of transmission error and reduction of the system availability [1]. Predicting rain attenuation is one of the vital steps to be considered when analyzing a satellite communication link. Adaptive code mechanism or adaptiv
