On Cognitive Interference Networks
— We study the high-power asymptotic behavior of the sum-rate capacity of multi-user interference networks with an equal number of transmitters and receivers. We assume that each...

Beacon-assisted spectrum access with cooperative cognitive transmitter and receiver
—Spectrum access is an important function of cognitive radios for detecting and utilizing spectrum holes without harming the legacy systems. In this paper, we propose novel coope...

Rate Region Frontiers for n-user Interference Channel with Interference as Noise
This paper presents the achievable rate region frontiers for the n-user interference channel when there is no cooperation at the transmit nor at the receive side. The receiver is a...

The Impact of CSI and Power Allocation on Relay Channel Capacity and Cooperation Strategies
Capacity gain from transmitter and receiver cooperation are compared in a relay network where the cooperating nodes are close together. Under quasi-static channels, when all nodes...
