This paper proposes an energy efficient collaborative cyclostationary spectrum sensing
approach for cognitive radio systems. An existing statistical hypothesis test for the presence …

Abundant resources of magnesium silicates make an interesting prospect for long-term
storage of CO2 by mineral carbonation. Several carbonation processes proposed in …

In this correspondence, an adaptive cooperation diversity scheme with best-relay selection
is proposed for multiple-relay cognitive radio networks to improve the performance of …

Cognitive radio is being intensively researched as the enabling technology for secondary
access to the so-called TV White Spaces (TVWS), large portions of spectrum in the UHF/VHF …

Abstract Machine-to-machine (M2M) communications emerge to autonomously operate to
link interactions between Internet cyber world and physical systems. We present the …

In the letter the problem of cooperative spectrum sensing is investigated in cognitive radio
(CR) networks over Rayleigh fading channels. By taking into account the error effect on the …

The massive growth in mobile users and wireless technologies has resulted in increased
data traffic and created demand for additional radio spectrum. This growing demand for …

It has been 20 years since the concept of cognitive radio (CR) was proposed, which is an
efficient approach to provide more access opportunities to connect massive wireless …

In this paper, optimal multi-channel cooperative sensing strategies in cognitive radio
networks are investigated. A cognitive radio network with multiple potential channels is …

In this paper, we investigate joint relay selection and power allocation to maximize system
throughput with limited interference to licensed (primary) users in cognitive radio (CR) …
