Cognitive radio (CR) provides a better way for utilization of spectrum resource by introducing
an opportunistic usage of the frequency bands that are not heavily occupied by a licensed …

Due to proliferation of wireless devices, communication over the crowded spectrum bands is
becoming increasingly di? cult and energy consuming. Therefore, a need arises to find an …

Driven by both the need for ubiquitous wireless services and the stringent strain on radio
spectrum faced in today's wireless communications, cognitive radio (CR) have been …

Cognitive Radio (CR) system is a radio system which is aware of its operational and
newlinegeographical environment, established policies and also its internal state. It is able …

Abstract Cognitive Radio Networks emerged as optimal solution for resolving spectrum
scarcity challenges due to its opportunistic nature of bandwidth utilization. CRN behaved as …

Cognitive Radio Networks (CRNs) have been proposed as a solution to the problem of
spectrum scarcity in wireless communication systems. CRNs allow for dynamic spectrum …

In cognitive radio networks, the media access control (MAC) protocols need to determine the
availability of spectrum resource through spectrum sensing and coordinate with the other …

Cognitive radio networks hold the key to achieving better radio bandwidth utilization and
improving the quality of wireless applications. The next step in this fast emerging paradigm …

Spectrum sensing is the most important function of the Cognitive Radio. One of the most
important challenges in the spectrum sensing is the detection of primary users in very short …

This chapter discusses the use of machine and deep learning in spectrum and resource
optimisation for the cognitive radio networks. Indeed, modern cognitive radio networks are …
