TLDR
New outer bounds are demonstrated for the capacity regions of discrete memoryless interference channels and Gaussian interference channels, which improves previous knowledge when the interference is of medium strength.Abstract:
New outer bounds are demonstrated for the capacity regions of discrete memoryless interference channels and Gaussian interference channels. The bound for discrete channels coincides with the capacity region in special cases. The bound for Gaussian channels improves previous knowledge when the interference is of medium strength.read more

A New Outer Bound and the Noisy-Interference Sum–Rate Capacity for Gaussian Interference Channels
TL;DR: It is shown that if the channel crosstalk coefficient magnitudes lie below thresholds defined by the power constraints then single-user detection at each receiver is sum-rate optimal, i.e., treating the interference as noise incurs no loss in performance.

Degrees of Freedom for the MIMO Interference Channel
TL;DR: It is shown through an example of a share-and-transmit scheme how the gains of transmitter cooperation may be entirely offset by the cost of enabling that cooperation so that the available DOF are not increased.

On the Gaussian interference channel
TL;DR: The optimality is established of two extreme points in the achievable region of the general Gaussian interference channel and it is proved that the class of degradedGaussian interference channels is equivalent to theclass of Z (one-sided) interference channels.

The capacity of the Gaussian interference channel under strong interference (Corresp.)
TL;DR: The capacity region of a Gaussian interference channel with two separate messages is obtained for the case of moderately strong interference and it is shown that the region coincides with the one where both messages are required in both receiving terminals.

A case where interference does not reduce capacity (Corresp.)
TL;DR: In this paper, it was shown that under certain conditions, two strongly interfering communication links with additive white Gaussian noise can achieve rates as high as would be achievable without this interference.

Recent results in the Shannon theory
TL;DR: The first part of this paper consists of short summaries of recent work in five rather traditional areas of the Shannon theory, namely: source and channel coding theorems for new situations, and calculation of source rate and channel capacity.
