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

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

In high-speed wireless communication systems, direct-conversion transceivers (DCTRs) are
in demand due to low implementation cost of analog front ends. However, the DCTRs are …

Direct conversion radios are widely recognized as the most appealing approach for
reducing the hardware cost as well as power consumption in upcoming communication …

Most spectrum sensing algorithms mainly use the characteristics of frequency, time, and
geographical dimensions to detect spectrum holes. In this paper, we propose a novel …

This letter concentrates on the spectrum sensing (SS) problem for noncircular (NC) signal in
multiantenna cognitive radio networks. A novel detection method called NC local average …

In this study, the authors study the collaborative data aggregation using multiple antennas
sensors and fusion centre (FC) with energy harvesting capability in the wireless sensor …

The wireless frequency spectrum is a very valuable resource in the field of communications.
Over the years, different bands of the spectrum were licensed to various communications …
