摘要：
A large multiple-input multiple-output satellite communication system is proposed, where satellite and Earth stations (ESs) contain a very large number of antennas. ESs want to exchange their data via a satellite. Data of transmitting ES is transmitted by using a beamforming vector. At the receiving ES, the data of unwanted ESs is canceled by utilizing null space based approach. Then a combining vector is used at the receiving ES in order to retrieve the data. It is observed that sufficiently large number of antennas at the ESs are needed by the proposed scheme. By following the standard moment generating function based approach, analytical results of symbol error rate of the proposed system are formulated.
