In this survey paper, we characterize the learning problem in cognitive radios (CRs) and
state the importance of artificial intelligence in achieving real cognitive communications …

This paper provides an overview of cognitive radio (CR) networks, with focus on the recent
advances in resource allocation techniques and the CR networks architectural design. The …

The explosive popularity of small-cell and Internet of Everything devices has tremendously
increased traffic loads. This increase has revolutionised the current network into 5G …

Joint communication and sensing (JCAS) is an emerging technology for managing efficiently
the scarce radio frequency (RF) spectrum, and is expected to be a key ingredient in beyond …

A cooperative approach to the sensing task of wireless cognitive radio (CR) networks is
introduced based on a basis expansion model of the power spectral density (PSD) map in …

Cognitive radio is a promising paradigm to achieve efficient utilization of spectrum resource
by allowing the unlicensed users (ie, secondary users, SUs) to access the licensed …

Cognitive radio systems necessitate the incorporation of cooperative spectrum sensing
among cognitive users to increase the reliability of detection. We have found that …

We consider the problem of spectrum trading with multiple licensed users (ie, primary users)
selling spectrum opportunities to multiple unlicensed users (ie, secondary users). The …

Maximization of the weighted sum-rate of secondary users (SUs) possibly equipped with
multiantenna transmitters and receivers is considered in the context of cognitive radio (CR) …

Currently, the radio spectrum is statically allocated and divided between licensed and
unlicensed frequencies. Due to this inflexible policy, some frequency bands are growing in …
