Grassmannian precoding MU-MIMO scheme
چکیده انگلیسی
In this article, a Grassmannian precoding multiuser multiple-input multiple-output (MU-MIMO) scheme for downlink transmission is proposed. The proposed MU-MIMO scheme will perform scheduling and precoding simultaneously at the base station, to obtain both the multiuser diversity gain and the precoding gain, to maximize the system capacity. The precoding method is related to Grassmannian precoding, which extends the point-to-point single-user Grassmannian precoding to point-to-multipoint multiuser Grassmannian precoding. It provides further significant system capacity enhancement than the single user MIMO (SU-MIMO) system and also outperforms the block diagonalization (BD) algorithm under the same simulation environment.
