Cooperation and Cognitive Radio [PDF]
2007 IEEE International Conference on Communications, 2007 Cooperation is increasingly regarded as a key technology for tackling the challenges of a practical implementation of cognitive radio. In this paper, we first give a brief overview of the envisioned applications of cooperative technology to cognitive radio, distinguishing among cooperative sensing for detection of the primary activity, cooperative ...

Resource Allocation for IRS-Assisted Full-Duplex Cognitive Radio Systems [PDF]
IEEE Transactions on Communications, 2020 In this article, we investigate the resource allocation design for intelligent reflecting surface (IRS)-assisted full-duplex (FD) cognitive radio systems. In particular, a secondary network employs an FD base station (BS) for serving multiple half-duplex

The impact of cognitive radio on radio astronomy [PDF]
Proceedings of RFI mitigation workshop — PoS(RFI2010), 2010 The introduction of new communication techniques requires an increase in the efficiency of spectrum usage. Cognitive radio is one of the new techniques that fosters spectrum efficiency by using unoccupied frequency spectrum for communications. However, cognitive radio will increase the transmission power density and cause an increasing level of Radio ...

Cognitive radio networks [PDF]
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.
