Multiple Weighting Matrices Selection Strategy for Orthogonal Random Beamforming Scheme
In this paper,a multiple weighting matrices selection Strategy for orthogonal random beamforming is discussed to increase the throughput of the multi-user MIMO systems.Multiple weighting matrices are performed and computed during the mini-slots.And the base station selects the best matrix based on the partial channel state information and performs the orthogonal random beamforming during the time slot.The proposed scheme over multi-user random beamforming can increase the throughput of multi-user MIMO system significantly,and the simulation results show the validity.
