Analysis of the Total Carrier-To-Noise Plus Interference Ratio Statistics Applied To Adjacent Satellite Interference Under the Presence of Rain

Abstract

Interference effects are of utmost importance to the reliable design of satellite communication systems. In this paper, interference caused by differential rain attenuation from an adjacent Earth-space system operating at the same frequency is considered as dominant. In particular, a method to predict rain differential attenuation statistics, used for noise-dominant systems, is extended to include the general case when the calculation of the degradation of the total carrier-to-noise plus interference ratio (CNIR) under the presence of rain fading conditions, is necessary. The method is again based on a model of convective raincells and on the lognormal assumption for point rainfall rate statistics. The numerical results are concentrated on the analytical examination of the influence of various operational parameters upon the CNIR statistics and the subsequent outage performance of the system.
