Cognitive radio has been proposed as a promising technology to resolve the spectrum scarcity problem by dynamically exploiting underutilized spectrum bands. Cognitive radio technology allows unlicensed users to exploit the spectrum vacancies at any time ...
We consider a wireless cognitive radio network in which a set of secondary users (SUs) opportunistically utilize the wireless spectrum licensed to the primary users (PUs) to transmit packets to the secondary base station (SBS). It is challenging to ...
The operation of cognitive radio (CR) networks involves opportunistic access to the spectrum licensed to primary users (PUs) by secondary users (SUs). Traditionally, this access is performed in such a way that the PUs suffer minimal interference to ...
