Effects of Imperfect Channel State Information on Achievable Rates of Precoded Multi-User MIMO Broadcast Channels with Limited F
—We consider multi-user MIMO broadcast channels with limited feedback. A recently proposed linear precoding technique, regularized block diagonalization (RBD), is used to mitigat...

Improved sum-rate optimization in the multiuser MIMO downlink
—We consider linear precoding and decoding in the downlink of a multiuser multiple-input, multiple-output (MIMO) system. In this scenario, the transmitter and the receivers may e...

Linear and Non-Linear Detection for MIMO-OFDM Systems with Linear Precoding and Spatial Correlation
Precoding at the transmitter side facilitates the use of linear MIMO detection schemes, which are attractive for low-complexity receiver implementations. However, their performance...
