Cooperative Wideband Spectrum Sensing Over Fading Channels [PDF]
IEEE Transactions on Vehicular Technology, 2016 In cognitive radio (CR) systems, it is crucial for secondary users to reliably detect spectral opportunities across a wide frequency range. This paper studies a novel multirate sub-Nyquist spectrum sensing (MS3) system capable of performing wideband spectrum sensing in a cooperative CR network over fading channels.
