On the capacity region of multiple-access relay channels
The capacity regions of two classes of multiple­ access relay channels (MARes) are characterized. The MARes studied in this paper include a primitive relay component, which can he...

From Multi-Keyholes to Measure of Correlation and Power Imbalance in MIMO Channels: Outage Capacity Analysis
An information-theoretic analysis of a multi-keyhole channel, which includes a number of statistically independent keyholes with possibly different correlation matrices, is given. ...

Outer Bounds for the Interference Channel with a Cognitive Relay
In this paper, we first present an outer bound for a general interference channel with a cognitive relay, i.e., a relay that has non-causal knowledge of both independent messages t...
