Internet of things (IoT) paradigm poses new challenges to the communication technology as
numerous heterogeneous objects will need to be connected. To address these issues new …

Opportunistic access has been considered by regulators for a number of different spectrum
bands. In this paper, we discuss and qualitatively evaluate techniques used in the discovery …

Spectrum sensing is a key function of cognitive radio to prevent the harmful interference with
licensed users and identify the available spectrum for improving the spectrum's utilization …

A promising technology that tackles the conflict between spectrum scarcity and
underutilization is cognitive radio (CR), of which spectrum sensing is one of the most …

The collaboration of users in communication systems is defined as cooperative
communication. The cognitive radio, ie dynamic spectrum access technique, is a wireless …

Smart grid is widely considered to be the next generation of power grid, where power
generation, management, transmission, distribution, and utilization are fully upgraded to …

Due to harsh environment, large number of sensors, limited energy, and spectrum scarcity,
intelligent sensing becomes a key issue to enable many practical applications in industrial …

Cognitive radio has been proposed as a promising technology to resolve the spectrum
scarcity problem by dynamically exploiting underutilized spectrum bands. Cognitive radio …

Due to the negative impact from spatial correlation, spatially correlated cognitive radio (CR)
based devices participating in cooperative spectrum sensing may be harmful to the …

In this paper, a comparison between energy and maximum–minimum eigenvalue (MME)
detectors is performed. The comparison has been made concerning the sensing complexity …
