Abstract
There are new system implementation challenges involved in the design of cognitive radios, which have both the ability to sense the spectral environment and the flexibility to adapt transmission parameters to maximize system capacity while co-existing with legacy wireless networks. The critical design problem is the need to process multi-gigahertz wide bandwidth and reliably detect presence of primary users. This places severe requirements on sensitivity, linearity, and dynamic range of the circuitry in the RF front-e ....etc

Cognitive architecture


A cognitive architecture is a blueprint for intelligent agents. It proposes (artificial) computational processes that act like certain cognitive systems, most often, like a person, or acts intelligent under some definition. It is a superset of general agent architectures. The term architecture implies an approach that attempts to model not only behavior, but also structural properties of the modelled system.
Characterization
Common to cognitive architecture is the belief that understanding (human) cognitive process ....etc

Title: cognitive radio systems

Abstract

Efficient use of radio spectrum is a necessity for future wireless systems. While the vast majority of the frequency spectrum is licensed to different organizations, observations provide evidence that usage of the licensed spectrum is by far not complete

neither in the time domain nor the spatial domain. This material discusses basics of Cognitive radio (CR), classifications of

cognitive radio systems, cognitive system architecture, antenna design for cognitive radio system.

Abstract—

Cognitive networks can potentially solve the
problems of spectrum scarcity by accommodating unlicensed
(secondary) users in under-utilized segments of the spectrum.
Spectrum sensing serves as the primary stimulus for a cognitive
radio an ....etc
