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...

On Achievable Rates of the Two-user Symmetric Gaussian Interference Channel
We study the Han-Kobayashi (HK) achievable sum rate for the two-user symmetric Gaussian interference channel. We find the optimal power split ratio between the common and private m...

When Feedback Doubles the Prelog in AWGN Networks
We demonstrate that the sum-rate capacity of a memoryless Gaussian network at high signal-to-signal ratio (SNR) can be asymptotically doubled when feedback is available. To demonst...

On the Rate Duality of MIMO Interference Channel and Its Application to Sum Rate Maximization
In this paper, we establish a rate duality between the forward and reverse links of MIMO interference channel, where the reverse links are obtained by exchanging the roles of trans...

The Capacity Region of a Class of Discrete Degraded Interference Channels
We provide a single-letter characterization for the capacity region of a class of discrete degraded interference channels (DDICs). The class of DDICs considered includes the discre...

On the Capacity and Generalized Degrees of Freedom of the X Channel
We explore the capacity and generalized degrees of freedom of the 2-user Gaussian X channel, i.e. a generalization of the 2-user interference channel where there is an independent...
