Distributed wideband spectrum sensing for cognitive radio networks [PDF]
2014 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2014 Wideband spectrum sensing improves the agility of spectrum sensing and spectrum hand-off in cognitive radio systems. In this paper, a distributed wideband spectrum sensing technique over adaptive diffusion networks is proposed. Considering unknown and different channels between the primary and the cognitive users, an averaged received power spectrum ...

Frequency‐domain wideband compressive spectrum sensing
IET Communications, 2016 The authors study the power spectrum density (PSD) estimation of wideband wide‐sense stationary (WSS) signals with sub‐Nyquist sampling rate. Owing to the large bandwidth, Nyquist rate sampling of such signals needs very high rate analogue‐to‐digital converters.
