| Abstract(in English) | Recently, Muti-User MIMO (MU-MIMO) downlink system which uses multiple antennas at base station and accommodates multiple users with multiple receive antennas attracts much attention. It can achieve a high channel capacity when the channel state information is known both at base station and each user. There exist linear and non-linear MU-MIMO downlink schemes, but the linear scheme is considered more easily to be implemented and adjusted. Linear Block Diagonalization (BD) has been proposed in order to cancel the Inter-User Interference (IUI), and combined with the Eigen-mode transmission. In this paper, by noting that the block size of each user matrix in BD becomes (number of receive antennas of each user) (nullity of the matrix constituted by other users), we design the BD + Eigen mode MU-MIMO scheme based on the down link quality of each user, i.e., the diversity order. We made simulations for some examples and show the effectiveness of the design method based on the user link quality. |
