摘要：
A multibeam satellite system can be modelled as a multiple-output (MIMO) system with an inter-beam interference matrix that is derived from the positions of the users in the different beams. This way it is possible to apply precoding techniques, such as Tomlinson-Harashima precoding (THP), to mitigate the interference. This paper presents an analytical framework to model the interference by a simple and effective parameter, which enables to assess the uncoded bit error rate (BER) of THP in such a scenario, and to derive useful hints on the optimization of the overall system capacity.
