Abstract :
The main propagation effect on interference between a satellite system and an adjacent microwave terrestrial path is the differential rain attenuation. In this paper, a method to predict rain differential attenuation statistics used for single site Earth-space systems, is extended to include dual site diversity systems. Just as with the original method the modified one is again based on a model of convective raincells and on the lognormal model for point rainfall rate statistics. The effects of various parameters on the diversity gain, corresponding to the carrier-to-interference ratio, are calculated numerically, leading to some very useful conclusions
