An improved ITU-R rain attenuation prediction model over terrestrial microwave links in tropical region

An improved approach of predicting rain attenuation cumulative distribution (CD) over terrestrial microwave links operating in tropical regions is presented in this article. The proposed method offers a better extrapolation approach for determining the values of rain attenuation at different excee...
