Inner and outer bounds are established on the capacity region of two-sender, two-receiver interference channels where one transmitter knows both messages. The transmitter with extr...

We investigate the limits of communication over the discrete-time Additive White Gaussian Noise (AWGN) channel, when the channel output is quantized using a small number of bits. W...

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...

Abstract--The sum capacity of the one-sided parallel Gaussian interference channel is shown to be a concave function of user powers. Exploiting the inherent structure of the proble...
