Secrecy capacity of a class of orthogonal relay eavesdropper channels
The secrecy capacity is developed for a class of relay channels with orthogonal components and a passive eavesdropper node. The relay and destination receive signals from the sourc...

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...

Multiuser broadcast erasure channel with feedback - capacity and algorithms
We consider the N-user broadcast erasure channel where feedback from the users is fed back to the transmitter in the form of ACK messages. We provide a generic outer bound to the ...

On an Outer bound and an Inner Bound for the General Broadcast Channel
In this paper, we study the Nair-El Gamal outer bound and Marton's inner bound for general two-receiver broadcast channels. We show that the Nair-El Gamal outer bound can be m...

Outer Bounds for Multiple Access Channels with Feedback using Dependence Balance
We use the idea of dependence balance to obtain a new outer bound for the capacity region of the discrete memoryless multiple-access channel with noiseless feedback (MAC-FB). We co...
