Spectrum sensing is one of the most essential components of cognitive radio since it detects
whether the spectrum is available or not. However, spectrum sensing accuracy is often …

Spectrum sensing is the important aspect of cognitive radio (CR). In order to use the vacant
spectrum, cognitive radio user must be able to identify the presence of empty spectrum …

Cognitive Radio is a promising solution to spectrum underutilization problem, highlighting
the concept of Dynamic Spectrum Access with two primary functions of efficient radio …

spectrum, cognitive radio user must be able to identify the presence of empty spectrum …

In this paper, we considered a cooperative spectrum sensing over fading and non-fading
channels. We proposed a model of a Rayleigh fading channel and a non-fading additive …

In hard decision cooperative spectrum sensing (CSS), each secondary user (SU) or simply
cognitive radio user (CR) senses the primary user (PU) activity via a Sensing channel (S …
