Precoding and feedback schemes for a MIMO backhaul link in the presence of interference
The focus of this paper is on the precoding and feedback strategies for a radio backhaul link between an access base station (ABS) and the hub base station (HBS) in the presence of...

Downlink MIMO Systems Using Cooperation Among Base Stations in a Slow Fading Channel
To increase the achievable sum rate of downlink MIMO (Multiple Input Multiple Output) systems, the cooperation among Base Stations (BS) is investigated in a slow fading channel. Th...

When Feedback Doubles the Prelog in AWGN Networks
We demonstrate that the sum-rate capacity of a memoryless Gaussian network at high signal-to-signal ratio (SNR) can be asymptotically doubled when feedback is available. To demonst...

Channel quantization design in multiuser MIMO systems: Asymptotic versus practical conclusions
Feedback of channel state information (CSI) is necessary to achieve high throughput and low outage probability in multiuser multiantenna systems. There are two types of CSI: direc...

On the ergodic capacity of jointly-correlated rician Fading MIMO channels
—In this paper, we study the capacity-achieving input covariance matrices for the jointly-correlated (or the Weichselberger) Rician fading multiple-input multiple-output (MIMO) a...
