Statistically Robust Design of Linear MIMO Transceivers
The treatment of channel state information (CSI) is critical in the design of MIMO systems. Accurate CSI at the transmitter is often not possible or may require high feedback rate...

A MIMO channel perturbation analysis for robust bit loading
In narrowband multiple-input multiple-output (MIMO) communication systems, when the channel state information (CSI) is known perfectly at the transmitter and the receiver, techniq...

Multiuser MIMO Downlink Transmission Over Time-Varying Channels
—— The performance of multiuser MIMO downlink systems with block diagonalization (BD) relies on the channel state information (CSI) at the transmitter to a great extent. For ti...
