Wide-band multipath A to D converter for Cognitive Radio applications

Abstract : This article presents a digital-enhanced radio frequency receiver for fast wide-band spectrum sensing. It is based on charge sampling and hybrid filter bank techniques. The charge sampling method is employed to design analog bandpass filters. Using a hybrid filter bank for wide-band analog-to-digital conversion improves the speed and resolution of the conversion. We propose to use these techniques in combination of frequencydivision multiplexing with time-division multiplexing to design an integrated, completely software reconfigurable and reliable backend of radio frequency receiver for cognitive radio applications.
