New Results on the Capacity of the Gaussian Cognitive Interference Channel
The capacity of the two-user Gaussian cognitive interference channel, a variation of the classical interference channel where one of the transmitters has knowledge of both messages...

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...

Outer bound and noisy-interference sum-rate capacity for symmetric Gaussian interference channels
A new outer bound on the capacity region of Gaussian interference channels is developed. The bound combines and improves existing genie-aided methods and is shown to give the sum-r...

Feedback Capacity of the Gaussian Interference Channel to within 2 Bits
We characterize the capacity region to within 2 bits/s/Hz and the symmetric capacity to within 1 bit/s/Hz for the two-user Gaussian interference channel (IC) with feedback. We dev...

Gaussian Interference Channel Capacity to Within One Bit
—The capacity of the two-user Gaussian interference channel has been open for 30 years. The understanding on this problem has been limited. The best known achievable region is du...
