To improve the spectral efficiency of a cellular network, sensing based spectrum sharing
device-to-device (sensing-based D2D) technique is introduced in this paper. To be specific …

Cognitive Radio is an able candidate, which can alleviate the spectrum underutilization
problem through Opportunistic Spectrum Access. The sensing of spectrum is the first step to …

In this paper, we extenuate the effect of malicious cognitive sensors (MCSs) from the optimal
combining of cooperative spectrum sensing scheme. We consider the cognitive radio …

This paper presents the performance evaluation of the Energy Detector technique, which is
one of the most popular Spectrum Sensing (SS) technique for Cognitive Radio (CR). SS is …

We consider a cognitive radio network with cooperative spectrum sensing (CSS) and
