Feasible Point Pursuit and Successive Approximation of Non-convex QCQPs

Omar Mehanna, Kejun Huang, Balasubramanian Gopalakrishnan +2

Quadratically constrained quadratic programs (QCQPs) have a wide range of applications in signal processing and wireless communications. Non-convex QCQPs are NP-hard in general. Ex…

On Achievable Rates of the Two-user Symmetric Gaussian Interference Channel

Omar Mehanna, John Marcos, Nihar Jindal

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…

Inter-Sensing Time Optimization in Cognitive Radio Networks

Omar Mehanna, Ahmed Sultan

We consider a set of primary channels that operate in an unslotted fashion, switching activity at random times. A secondary user senses the primary channels searching for transmiss…

Cognitive MAC Protocols for General Primary Network Models

Omar Mehanna, Ahmed Sultan, Hesham El Gamal

We consider the design of cognitive Medium Access Control (MAC) protocols enabling a secondary (unlicensed) transmitter-receiver pair to communicate over the idle periods of a set…

Blind Cognitive MAC Protocols

Omar Mehanna, Ahmed Sultan, Hesham El Gamal

We consider the design of cognitive Medium Access Control (MAC) protocols enabling an unlicensed (secondary) transmitter-receiver pair to communicate over the idle periods of a set…
