In this paper, we consider an efficient decision fusion technique for cooperative spectrum
sensing based on the logical OR-rule for dynamic spectrum sharing among primary and …

As the role of wireless communication is becoming more important for realizing a future
connected society for not only humans but also things, spectrum scarcity is becoming …

Amidst conflicting views about whether soft cooperative energy detection scheme (SCEDS)
outperforms hard cooperative energy detection scheme (HCEDS) greatly in cognitive radio …

Cognitive radio (CR) is the key technology for unlicensed secondary users (SUs) to exploit
the unused spectrum of primary users (PUs) via opportunistic spectrum access. In CR …

Automatic modulation classification (AMC) is crucial for electronic warfare, spectrum
monitoring, and cognitive radios. Traditional methods, relying on maximum likelihood …

Enhancing the current services or deploying new services operating in RF spectrum
requires more licensed spectrum which may not be provided by the regulatory bodies …

Dynamic spectrum access (DSA) is an attractive approach to solve the spectrum scarcity
problem. Among DSA techniques, spectrum overlay is an approach where the spectrum …

Free probability theory, which has become a main branch of random matrix theory, is a
valuable tool for describing the asymptotic behavior of multiple systems, especially for large …

Spectrum sensing is the most important task among others for the effective operation of
cognitive radio networks. Spectrum sensing enables the capability of a cognitive radio to …

Spectrum sensing, as a key technology in cognitive radio networks, needs to detect signals
