Rain attenuation and cross-polarization effects in interference between adjacent satellite and terrestrial dual polarized systems

In the present paper a novel method to predict the degradation of the carrier-to-interference ratio, due to rain attenuation-depolarization, on a satellite system interfered by an adjacent terrestrial microwave link is proposed. This method refers to the case that both communication systems operate under the dual polarization mode. It is based on a model convective rain cell structure of the rainfall medium as well as the assumption that both the point rainfall statistics and the rain attenuation follow a lognormal distribution. Numerical results are presented referring to communication systems operating in Italy.
