The secondary users can opportunistically utilize the spectrum holes left by the licensed
users (also called primary users PUs) with the help of cognitive radio (CR) technology. The …

Spectrum scarcity has evolved as a challenging problem in the field of wireless
communication. Cognitive radio (CR) has emerged as a solution to this problem which uses …

This paper incorporates interference cancellation in the outage analysis of a wireless energy
harvesting cognitive relay network. Based on an interference threshold, primary receivers …

This study presents an analytical method that shows how spatial correlation degrades the
overall performance of cooperative spectrum sensing. In a cooperative spectrum sensing …

The cognitive radio (CR) technology is developed to help secondary users to utilize
spectrum holes of the primary users (PUs) opportunistically. Accurate detection of spectrum …

Increasing demand for services such as mobile telephones and many others has introduced
a need for a fresh perspective on spectrum utilization and management. A promising …

Since spectrum is the invisible infrastructure that powers the wireless communication, the
