Cognitive radio is a promising solution to current problem of spectrum scarcity. It relies on
efficient spectrum sensing. Energy detection is the most dominantly used spectrum sensing …

Cognitive radios are expected to play an important role in capturing the constantly growing
traffic interest on remote networks. To improve the usage of the radio range, a cognitive …

Spectrum scarcity is impeding practical implementations of emerging wireless multimedia
applications requiring significantly more frequency spectrum. Cognitive radio (CR) has …

To improve the efficiency of bandwidth usage, the cognitive radios concept has emerged.
Spectrum sensing is a pivotal function in cognitive radio systems so that the secondary users …

Cognitive Radio (CR) has emerged as a smart solution to spectrum bottleneck faced by
current wireless services under which licensed spectrum is made available to unlicensed …

In wireless networks, field resources in terms of frequency and bandwidth availability are
