A Transmit Preprocessing Technique for the Multi-user MIMO System Downlink

摘要：

A novel transmit preprocessing technique for the multiuser multiple-input multiple-output (MIMO) downlink is presented in this paper. Combined with the signal to jamming and noise ratio maximization method (SJNR), this proposed method can suppress the multi-user interference (MUI) effectively. More importantly, the multi-stream peruser interference can also be cancelled simultaneously at the transmitter, and the post-processing matrix in traditional methods is not required. Therefore, the new scheme has reduced the receivers complexity.
