Towards the Secrecy Capacity of the Gaussian MIMO Wire-tap Channel: The 2-2-1 Channel
—We find the secrecy capacity of the 2-2-1 Gaussian MIMO wiretap channel, which consists of a transmitter and a receiver with two antennas each, and an eavesdropper with a singl...

A convex approximation approach to weighted sum rate maximization of multiuser MISO interference channel under outage constraint
This paper considers weighted sum rate maximization of multiuser multiple-input single-output interference channel (MISO-IFC) under outage constraints. The outage-constrained weig...

On the Sum-Rate of Opportunistic Beamforming Schemes with Multiple Antennas at the Receiver
Abstract— The capacity region of Gaussian Multi-InputMultiple-Output (MIMO) broadcast channels has been shown to be achieved by dirty paper coding (DPC). However, due to the high...
