The Gaussian MAC with Conferencing Encoders
We derive the capacity region of the Gaussian version of Willems's two-user MAC with conferencing encoders. This setting differs from the classical MAC in that, prior to each ...

Optimal Cross-Layer Scheduling of Transmissions Over a Fading Multiaccess Channel
We consider the problem of several users transmitting packets to a base station, and study an optimal scheduling formulation involving three communication layers, namely, the mediu...

Transmission of common, public and confidential messages in broadcast channels with multiple antennas
Abstract-- We study the Gaussian multiple-input multipleoutput (MIMO) wiretap channel, which consists of a transmitter, a legitimate user, and an eavesdropper. In this channel, the...

Outage exponents of block-fading channels with power allocation
Power allocation is studied for fixed-rate transmission over block-fading channels with arbitrary continuous fading distributions and perfect transmitter and receiver channel state...

Cognitive radios with multiple antennas exploiting spatial opportunities
In this paper, the achievable rates of the so called "multiple-input multiple-output interference channel", exploited by a couple of single antenna primary terminals and...
