On the Statistics and MAC Implications of Channel Estimation Errors in MIMO Ad Hoc Networks
—In this paper, we propose an analytical technique to evaluate the statistics of the channel estimation error in a simple multi-user ad hoc networking scenario. This problem is v...

Adaptive Modulation for MIMO Systems with Channel Prediction Errors
The performance of multiple-input multiple-output (MIMO) systems using spatial multiplexing is analyzed under channel prediction errors. We derive exact closed-form expressions for...

Regularized Channel Inversion for Multiple-Antenna users in Multiuser MIMO Downlink
— Channel inversion is one of the simplest techniques for multiuser downlink systems with single-antenna users. In this paper, we extend the regularized channel inversion 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...

Amplify-and-Forward Capacity with Transmit Beamforming for MIMO Multiple-Relay Channels
In this paper, we consider a MIMO wireless relay network where communication between a source and a destination node is assisted by multiple relay nodes using the Amplifyand-Forwar...
