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...

Dirty-Paper Coding without Channel Information at the Transmitter and Imperfect Estimation at the Receiver
—In this paper, we examine the effects of imperfect channel estimation at the receiver and no channel knowledge at the transmitter on the capacity of the fading Costa’s channel...

Asynchronous Iterative Water-Filling for Gaussian Frequency-Selective Interference Channels
This paper considers the maximization of information rates for the Gaussian frequency-selective interference channel, subject to power and spectral mask constraints on each link. T...
