ACM SIGCOMM Computer Communication Review, 2013 A large volume of research has been conducted in the cognitive radio (CR) area the last decade. However, the deployment of a commercial CR network is yet to emerge. A large portion of the existing literature does not build on real world scenarios, hence, neglecting various important aspects of commercial telecommunication networks.

Cognitive radio networks [PDF]
IEEE Signal Processing Magazine, 2008 In recent years, the development of intelligent, adaptive wireless devices called cognitive radios, together with the introduction of secondary spectrum licensing, has led to a new paradigm in communications: cognitive networks. Cognitive networks are wireless networks that consist of several types of users: often a primary user (the primary license ...

Trusted cognitive radio networking [PDF]
Wireless Communications and Mobile Computing, 2009 AbstractNetworking cognitive radios and nodes from primary system (PS) results in a heterogeneous coexisting multi‐radio wireless network, so that significant network throughput gain can be achieved. However, by investigating cognitive radio network (CRN) architecture, the links in CRNs are unlikely to support complete security check due to link ...

Design and characteristic analysis of hybrid OFD–LFM–PC waveforms in the MIMO radar
The Journal of Engineering, 2019 In this study, a new set of hybrid orthogonal frequency division–linear frequency modulation–phase coded (OFD–LFM–PC) waveforms are proposed to improve the detection performance of multiple-input-multiple-output (MIMO) radars.
