Abstract : | This paper proposed a low complexity and overhead multiple-user-multiple-input multiple-output (mu-MIMO) beamforming algorithm for low earth orbit (LEO) satellite communication systems with global navigation satellite system (GNSS). To be specific, the estimated channel based on the angle of arrival and departure (AoA, AoD) is used in beamforming. Simulation results show that the proposed algorithm has a performance very close to conventional beamforming algorithms, with low overhead and complexity. |
