This dissertation provides the theory, design, and implementation of a cognitive engine, the
enabling technology of cognitive radio. A cognitive radio is a wireless communications …

This cutting-edge resource offers practical overview of cognitive radio, a paradigm for
wireless communications in which a network or a wireless node changes its transmission or …

A cognitive radio (CR) is a transceiver that is aware, adaptive, and capable of learning. It
may be visualized and realized as an intelligent software package (cognitive engine) …

We can think of a cognitive radio as having three basic parts that make it cognitive: the ability
to sense, including at a minimum sensing the RF spectrum, geographical surroundings, and …

Intelligence is needed to keep up with the rapid evolution of wireless communications,
especially in terms of managing and allocating the scarce, radio spectrum in the highly …

This paper presents a genetic‐algorithm driven, cognitive radio decision engine that
determines the optimal radio transmission parameters for single and multicarrier systems …

Cognitive radio offers the promise of intelligent radios that can learn from and adapt to their
environment. To date, most cognitive radio research has focused on policy-based radios that …

This paper approaches cognition on the physical and MAC layers by defining a common
language of" knobs" and" meters" to discuss adaptation and learning. Cognitive radio …

The author presents a unified treatment of this highly interdisciplinary topic to help define the
notion of cognitive radio. The book begins with addressing issues such as the fundamental …

This research focuses on developing a cognitive radio that could operate reliably in
unforeseen communications environments like those faced by the disaster and emergency …
