Multiple-Input Multiple-Output Gaussian Broadcast Channels With Common and Confidential Messages
This paper considers the problem of the multiple-input multiple-output (MIMO) Gaussian broadcast channel with two receivers (receivers 1 and 2) and two messages: a common message ...

Covert and Side Channels Due to Processor Architecture
Information leakage through covert channels and side channels is becoming a serious problem, especially when these are enhanced by modern processor architecture features. We show ...

MIMO Broadcast Channels with Finite Rate Feedback
Multiple transmit antennas in a downlink channel can provide tremendous capacity (i.e. multiplexing) gains, even when receivers have only single antennas. However, receiver and tra...

Outage Capacity of the Fading Relay Channel in the Low SNR Regime
In this paper we look at the outage capacity of the fading relay channel with half-duplex constraint in the low SNR regime. First we consider the scenario that the channel state i...

New Outer Bounds on the Capacity Region of Gaussian Interference Channels
Abstract-- An outer bound on the capacity region of the twouser Gaussian interference channel is derived. The bound shows that for low power and small crosstalk coefficients the su...
