MIMO dual polarized fixed satellite systems above 10GHz: channel modeling and outage capacity evaluation

In this paper, the performance of a dual polarized MIMO fixed satellite system under rain is investigated. Due to the increase of capacity that is observed from MIMO terrestrial communications, the later techniques are also tested and evaluated in satellite communications. In this paper, a dual polarization satellite system is considered operating at frequencies above 10 GHz (e.g. Ka-band). Using multi-dimensional Stochastic Differential Equations (SDEs), the outage capacity of spatial multiplexing technique is investigated and compared fairly to the single polarization system. A gain is observed from results especially in periods with low rain attenuation.
