Acceptable intersystem interference probability distribution between adjacent terrestrial and satellite networks operating above 10 GHz

Abstract

The present paper studies, interference issues arising from, the spectral and spatial coexistence between terrestrial stations participating in fixed wireless networks or in a point-to-point link and satellite terminals belonging to a satellite communication network, operating at frequencies above 10 GHz. Rain attenuation is considered to be the dominant fading mechanism at this frequency range. The acceptable intersystem interference probability AIIP of the carrier-to-interference ratio CIR of a terrestrial station interfered by a satellite is defined and analytically calculated. Adaptive power control schemes are assumed to operate for both networks. The correlated propagation fading phenomena over multiple terrestrial and slant paths are accurately incorporated. The proposed model is physical and can be applied on a global scale since incorporates properly the local climatic conditions concerning the point rainfall rate and the spatial rainfall inhomogeneity. Useful numerical results of the present model are finally provided and the impact of various crucial operational and geometrical parameters of satellite and fixed wireless networks' coexistence is also examined.
