The Gerschgorin circle theorem was recently applied to build two detectors for the purpose
of spectrum sensing in cognitive radio applications, the so-called Gerschgorin radius-based …

We investigate spectrum sensing in cognitive radios with large antenna arrays. Gigantic
MIMO and extra-large array antennas are fundamental technologies in 5G and future 6G …

We design an optimal non-uniform quantizer for collaborative spectrum sensing (CSS) in
cognitive radio networks (CRNs). We assume non-ideal reporting channels are and consist …

In this paper, we study the spectrum sensing problem when the sensing device is equipped
with an uncalibrated multiantenna array. We consider an unknown Toeplitz structure for the …

This paper concerns covariance matrix-based spectrum sensing over frequency-selective
channels. The impact of frequency-selective channels on the covariance matrix of received …

We propose a general multiple antennas' detector for spectrum sensing in cognitive radios
based on complex Rao test. In contrast with conventional spectrum sensing detectors, we do …

This paper addresses the performance, the reporting channel traffic and the computational
complexity of two blind centralized cooperative spectrum sensing schemes under the effect …

Adopting cognitive radios (CRs) having multiple antennas in blind non-cooperative and
cooperative spectrum sensing (CSS) under fading channels has gained attention due to …

In this paper, based on the spectrum sensing problem of the primary user signal in low SNR
environment, an improved random forest spectrum sensing algorithm is proposed by using …

Nowadays, Cognitive Radio (CR) is projected as the technology that will maximize the
utilization of the spectrum resources in next generation wireless systems. Therefore, the …
