Spectrum Sensing (SS) plays an essential role in Cognitive Radio (CR) networks to
diagnose the availability of frequency resources. In this paper, we aim to provide an in-depth …

As we advance towards 6G communication systems, the number of network devices
continues to increase resulting in spectrum scarcity. With the help of Spectrum Sensing (SS) …

In recent times, wireless communication systems have been considered by a fixed spectrum
allocation policy, where administrative agencies provide wireless spectrum to licensees on a …

In this article, a novel spectrum sensing technique for cognitive radio (CR) is proposed
where eigenvalues of the covariance matrix of the received signal are used as features for …

In recent years, with the rapid development in wireless communication and 5G networks, the
rapid growth in mobile users has been accompanied by an increasing demand for the …

Spectrum sensing is a vital element of cognitive radio networks. It's the basis for unlicensed
users to access underutilized bands without disturbing licensed or primary users (PUs) …

Cognitive radios are expected to play an important role in capturing the constantly growing
traffic interest on remote networks. To improve the usage of the radio range, a cognitive …
