Blind Sub-Nyquist Spectrum Sensing With Modulated Wideband Converter

open access: yesIEEE Transactions on Vehicular Technology, 2018
Rooted in the compressed sensing theory, sub-Nyquist spectrum sensing (SNSS) has been considered as a promising approach to dealing with difficulties and limitations of conventional wideband spectrum sensing in cognitive radio (CR) networks. Most existing SNSS methods require some prior knowledge of the monitored frequency bands, such as the spectrum ...
