Abstract

We have proposed and discussed a method to transform rain attenuation probability distributions from fixed to mobile satellite communication systems. For a given outage probability, the power margin needed in the mobile system may be larger or smaller than that in the fixed system, depending on the speed of the vehicle relative to that of the rain storm. Simulations performed using experimental information on vehicle and rain storm speeds show that the probability distribution of the mobile system can be obtained from that of the fixed system, by multiplication of a factor which approximately varies between 0.5 and 2.0, independent of attenuation. The first is a realistic value obtained by averaging over all the possible directions of arrival of vehicles
