The radio resource shortage is one of the most important characteristic to take into account when deploying modern wireless telecommunication systems. A novel communication paradigm named Cognitive Radio, has been introduced in the last years for better exploiting the limited available spectrum and the inefficiency in the spectrum usage. Its main aim is to allow the co-existence of different wireless systems on the same spectral resource by limiting the mutual interference. One of the main challenge is to extend the cognitive paradigm also to satellite networks by considering hybrid satellite and terrestrial scenarios. Aim of this paper is to evaluate the coexistence of terrestrial and satellite networks by considering a cognitive approach when radio resource sharing is employed. The paper deals with the presentation of a statistical interference model that aims at evaluating the mutual interference among the two systems.

Abstract
The radio resource shortage is one of the most important characteristic to take into account when deploying modern wireless telecommunication systems. A novel communication paradigm named Cognitive Radio, has been introduced in the last years for better exploiting the limited available spectrum and the inefficiency in the spectrum usage. Its main aim is to allow the co-existence of different wireless systems on the same spectral resource by limiting the mutual interference. One of the main challenge is to extend the cognitive paradigm also to satellite networks by considering hybrid satellite and terrestrial scenarios. Aim of this paper is to evaluate the coexistence of terrestrial and satellite networks by considering a cognitive approach when radio resource sharing is employed. The paper deals with the presentation of a statistical interference model that aims at evaluating the mutual interference among the two systems.File | Dimensione | Formato | |
