The eigenvalues of the sample covariance matrix can capture signal correlations and noise
characteristics well, which are widely used for spectrum sensing in cognitive radio networks …

In this paper, we propose a reconfigurable intelligent surface (RIS) enhanced spectrum
sensing system, in which the primary transmitter is equipped with a single antenna, the …

This comprehensive reference text discusses concepts of cognitive radio and the advances
in the field of spectrum sensing. This text discusses the concept of cognitive radio for next …

In this article, we investigate the spectrum-sharing for a space information network
comprised of a geostationary orbit (GEO) satellite and a pair of low earth orbit (LEO) …

We investigate the spectrum sensing problem in a single-input-multiple-output cognitive
radio system under in-phase and quadrature imbalance (IQI). To do this, the received signal …

State-of-the-art energy detection (ED) based spectrum sensing requires perfect knowledge
of noise power and is vulnerable to noise uncertainty. An eigenvalue-based spectrum …

This paper creates a framework for spectrum sensing (SS) in localized Long-Term Evolution
(LTE)-based cognitive radios. The framework includes the formulation of various SS …

The increased interest in full-duplex communication combined with spectrum utilization
enhancements stemming from cognitive radio motivate research activities in full-duplex …

In this letter, we consider the issue of detecting signal of interest under interference. Two
multi-antenna based spectrum sensing algorithms are presented given the knowledge of …

Recently, sub-Nyquist sampling (SNS) based wideband spectrum sensing has emerged as
a promising approach for cognitive radios. However, most of existing SNS-based …
