Cognitive radio is an emerging wireless technology that is capable of efficiently coordinating
the use of the currently scarce spectrum resources, and spectrum sensing constitutes its …

Cognitive radio (CR) is considered an important solution to the current spectral scarcity,
which is expected to be a significant issue in the next generation of wireless communication …

Cognitive radio systems allow opportunistic secondary users (SUs) to access portions of the
spectrum that are unused by the network's licensed primary users (PUs), provided that the …

We study the impact of residual radio frequency (RF) impairments and fading on the
spectrum sensing performance of a classical energy detector (ED), which is employed in a …

Cognitive radio (CR) technology with dynamic spectrum management capabilities is widely
advocated for utilizing effectively the unused spectrum resources. The main idea behind CR …

Ultra high definition radio, low latency, high bandwidth, machine to machine communication
and several emergence application like e-health, IOT etc. will be dominated by 5G in future …

We consider a cognitive radio (CR) network consisting of a primary cellular system and a
secondary cognitive machine-to-machine (M2M) system, and study the throughput …

Bio‐inspired techniques, including firefly algorithm, fish school search, and particle swarm
optimisation, are utilised in this study to evaluate the optimal weighting vectors used in the …

In this paper, we propose an energy-efficient resource allocation (RA) algorithm in cognitive
radio-enabled 5th generation (5G) systems, where the scenario including one primary …
