Precoding performance in satellite communications

This project deals the performances of precoding technique in satellite communications. Satellite system use multi-beam coverage to increase its throughput and capacity through the geometrical deployment of contiguos beam. In order to mitigate the interference between adjacent beams, the Minimum Mean Square Error has been implemented to evaluate its performances in terms of achievable rate. The scenario is made up an antenna pattern array placed on geostationary satellite in clear sky condition and with full frequency reuse. The document contain a simulation of real scenario in which mathematical model of satellite architecture is implemented through the design of an antenna pattern array and its relative coverage. Later, the Minimum Mean Square Error estimation channel has been applied to the system to study its behavior. The reported results shown a link between the antenna parameters and the rate suggesting a solution for the optimization of precoding.
