Channel capacity limit of multi-beam satellite system

Abstract The requests of broadband coverage area and the expected user demand is satisfied by satellite industry using multiple spot beams high throughput satellites with fixed multi-beam pattern footprint planning. technology core high-throughput technology, means to efficiently reuse spectrum a full-frequency scheme. In order study channel capacity limit systems, Wiener-Gaussian access model terrestrial cellular systems analyzed in this paper. This paper analyzes then considers difference between spatial characteristics gain system compared system, proposes Wiener suitable for communication system. On basis, under different fading conditions deduced when optimal linear precoding minimum mean square error precoding. It provides theoretical support in-depth mechanism performance satellites.
