A single-letter achievable rate region is proposed for the two-receiver discrete memoryless broadcast channel with noiseless or noisy feedback. The coding strategy involves block-...
In this paper, we consider the Gaussian multiple-input multiple-output (MIMO) multi-receiver wiretap channel in which a transmitter wants to have confidential communication with ...
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...

The capacity region of a broadcast channel consisting of k-receivers that lie in a less noisy sequence is an open problem, when k 3. We prove that superposition coding is indeed ...
The sum-capacity is studied for a K-user physically degraded Gaussian multiaccess relay channel (MARC). Decodeand-forward (DF) is shown to achieve the sum-capacity and capacity reg...
