Spectrum sensing is of crucial importance in cognitive radio (CR) networks. In this paper, a
reliable spectrum sensing scheme is proposed, which uses K‐nearest neighbor, a machine …

The spectrum sensing performance depends on the accuracy of the detection about whether
primary users are busy or idle. Previous studies on cognitive radio spectrum sensing have …

In recent times, spectrum sensing and spectrum management become a crucial design
issue in cognitive radio networks (CRN). To improve the spectrum utilization in CRN, the …

Spectrum handoff has an undesirable effect in utilizing the space for Secondary user (SU) in
the spectrum, which causes a handoff delay in cognitive radio network. The SU frequently …

A cooperative cognitive radio (CR) network with multiple secondary users (or CRs) is
considered. Each CR consists of an arbitrary M number of antennas. For spectrum sensing …

The trade‐off between sensing time and throughput is investigated in the context of an
energy‐efficient cognitive radio network considering both the sensing and reporting …

The spectrum detection (SD) is a critical step in cognitive radio (CR) to identify the available
spectrum and avoid interference and harm to primary users (PUs). Nonetheless, the …

An encouraging technology that grabs the clash between spectrum scarcity and
underutilization is cognitive radio (CR), spectrum sensing is the main task of cognitive radio …

Deep semantic networks using sentimental mining is a powerful tool for analyzing user
sentiment in a wide range of contexts. Sentimental mining extracts and analyzes user …

In wireless communication, noise and fading affect the radio signals. Multiple antennas one
of the solutions to nullify these affects. In this paper, authors proposed an improved sensing …
