Due to the under-utilization problem of the allocated radio spectrum, cognitive radio (CR)
communications have recently emerged as a reliable and effective solution. Among various …

Cognitive radio (CR) is the enabling technology for supporting dynamic spectrum access:
the policy that addresses the spectrum scarcity problem that is encountered in many …

With the development of wireless communication technology, the need for bandwidth is
increasing continuously, and the growing need makes wireless spectrum resources more …

In this paper, we investigate cooperative spectrum sensing (CSS) in a cognitive radio
network (CRN) where multiple secondary users (SUs) cooperate in order to detect a primary …

Spectrum sensing is a key function of cognitive radio to prevent the harmful interference with
licensed users and identify the available spectrum for improving the spectrum's utilization …

We propose novel cooperative spectrum sensing (CSS) algorithms for cognitive radio (CR)
networks based on machine learning techniques which are used for pattern classification. In …

Cognitive radio is widely expected to be the next Big Bang in wireless communications.
Spectrum sensing, that is, detecting the presence of the primary users in a licensed …

Widely regarded as one of the most promising emerging technologies for driving the future
development of wireless communications, cognitive radio has the potential to mitigate the …

Cognitive radio (CR) can successfully deal with the growing demand and scarcity of the
wireless spectrum. To exploit limited spectrum efficiently, CR technology allows unlicensed …

In this letter, a resource allocation strategy based on a deep neural network (DNN) is
