“…Few direct experimental investigations of the performance of multiple‐site diversity systems have been done in the past; Tang et al [1982] discuss the results of a three‐site experiment carried out in Florida at 19 GHz over a period of 29 months. Witternigg et al [1993] used 12 GHz radiometers to simulate a quadruple‐site diversity satellite link. Goldhirsh et al [1997] describe a three‐site diversity experiment at 20 GHz using the Advanced Communications Technology Satellite (ACTS).…”

[1] The number of satellite telecommunication systems that make use of frequencies higher than 10 GHz is constantly growing; at frequencies above 10 GHz, attenuation due to rain can be a limiting factor for system availability; the dual-site diversity technique has proved to be quite useful in counteracting rain attenuation. This technique can be extended by adopting a multiple-site configuration. In this paper the performance of small-scale multiple-site diversity systems is investigated through simulations, carried out by exploiting a large database of radar maps of precipitation. Results have shown significant improvements in terms of diversity advantage and site separation reduction with respect to the dual-site configuration. Moreover, if the stations carry data traffic and they are not working at their full capacity, it is possible to recover a significant amount of the traffic that otherwise would be lost.Citation: Capsoni, C., and M.

Abstract. One of the main propagation effects 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 interfered Earth-space systems, is extended to include double-site diversity systems. The modified method is again based on a model of convective rain cells as well as on the lognormal assumption for the point rainfall rate distribution at the location under consideration. Numerical results are presented concerning a realistic interfered satellite link using double-site diversity and located in Japan. Because of a lack of available experimental data, our attention has mainly been concentrated on the examination of the optimum coordination between the adjacent systems. Some very useful conclusions are deduced.
