In this paper, we consider a doubly constrained underlay cognitive radio (CR) system. In it, a secondary user (SU) transmitter (Tx) is subject to average interference constraint, and spectral efficiency constraint. For the ...

We consider a two hop cooperative device-to-device (D2D) communication system. In it, a non-regenerative relay is subject to a tight constraint on the average interference it to the base station (BS). We derive interference-aware, ...

Two models for AF relaying, namely, fixed gain and fixed power relaying, have been extensively studied in the literature given their ability to harness spatial diversity. In fixed gain relaying, the relay gain is fixed but ...

Opportunistic interference alignment (OIA) is a well known precoding technique that uses interference alignment to improve the rate of secondary user (SU) simultaneously nullifying the interference that SU causes to a ...
