Abstract

A modification to an effective path length for predicting rain attenuation in Malaysia is proposed in this paper. Due to the scarcity of actual signal measurements at high frequencies-bands in tropical climates make predicted models are key resource for generating rain attenuation. A modification to calculate the effective path length is introduced in the original model. A control parameter rho is also induced based on the rain intensity variations along the slant path. A new value is suggested according to measurements in Malaysia. The results showed that modified rain attenuation model has significantly improved the rain attenuation prediction in Malaysia.
