System Design Considerations for an Analog Frontend Receiver in Cognitive Radio Applications
Sandro Binsfeld Ferreira, Filipe D. Baumgratz, Sérgio Bampi · 2013
This article presents a brief overview of the Cognitive Radio technology and applications, focusing in the Standard IEEE 802.22 as well as in an extension of the frequency band application to the range of 54 MHz to 4 GHz. A direct conversion strategy is proposed and the receiver scenery is taken into account in order to present standard targets for the main receiver specifications such as noise figure, sensitivity and linearity. Keywords— Cognitive Radio, IEEE802.22, direct conversion, receiver architecture, receiver linearity.
