Abstract:Abstract-Wideband spectrum sensing is a challenging task due to the constraints of digital signal processing (DSP) unit using in extant wireless systems. Compressive sensing (CS) is a new paradigm in signal processing, chosen for sparse wideband spectrum estimation with compressive measurements, thus provides relief of high-speed DSP requirements of cognitive radio (CR) receivers. In CS, whole wideband spectrum is estimated to find an opportunity for a CR usage requiring significant computation as well as sens… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
