Publikováno v: IEEE Transactions on Antennas and Propagation. 67:475-483

A statistical model to predict the effects of both rain and clouds on the earth–space site diversity communication systems is presented. The methodology relies on the assumption, already widely considered in the literature, that both rain- and clou
