The ever-increasing demand for higher data rates in wireless communications in the face of
limited or underutilized spectral resources has motivated the introduction of cognitive radio …

Cognitive radio (CR) can successfully deal with the growing demand and scarcity of the
wireless spectrum. To exploit limited spectrum efficiently, CR technology allows unlicensed …

Cognitive radio is a promising technology that enables an unlicensed user (also known as a
cognitive user) to identify the white space of a licensed spectrum band (called a spectrum …

Cooperative spectrum sensing has proven its efficiency to detect spectrum holes in cognitive
radio network (CRN) by combining sensing information of multiple cognitive radio users. In …

This paper develops a solution for the problem of uncorrelated user selection in mobile
cognitive radio ad hoc networks, with the objective to increase the performance of …

Spectrum sensing for cognitive radio allows a secondary user to detect spectrum 'holes' and
to opportunistically exploit this space for unlicensed communication. Blind spectrum sensing …

Spectrum sensing is an important step toward enabling dynamic spectrum access in
cognitive radio networks. To ensure that primary users are properly protected while …

Cognitive radio networks sense spectrum occupancy and manage themselves to operate in
unused bands without disturbing licensed users. The detection capability of a radio system …

We consider novel cooperative spectrum sensing (CSS) algorithms based on the pattern
classification techniques for cognitive radio (CR) networks. In this regard, support vector …

We propose a new framework for cooperative spectrum sensing in cognitive radio networks,
that is based on a novel class of nonuniform samplers, called the event-triggered samplers …
