| Research Abstract |
In this research, I proposed several downlink multi-user MIMO (MU-MIMO) transmission schemes to achieve high capacity according to the available channel state information (CSI). First I proposed the user-selection for MU-MIMO using channel prediction for time-varying channel. Second, I proposed the resource allocation based on users' requirements for QoS and CSI. Moreover, I proposed an orthogonal beamforming method using Gram-Schmidt orthogonalization. I showed the effectiveness of each proposed method.
