One-Bit Spectrum Sensing in Cognitive Radio Sensor Networks [PDF]
Circuits, Systems, and Signal Processing, 2019 This paper proposes a spectrum sensing algorithm from one bit measurements in a cognitive radio sensor network. A likelihood ratio test (LRT) for the one bit spectrum sensing problem is derived. Different from the one bit spectrum sensing research work in the literature, the signal is assumed to be a discrete random correlated Gaussian process, where ...

Distributed compressed wideband sensing in Cognitive Radio Sensor Networks [PDF]
2011 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS), 2011 A novel distributed compressed wideband sensing scheme for Cognitive Radio Sensor Networks (CRSN) is proposed in this paper. Taking advantage of the distributive nature of CRSN, the proposed scheme deploys only one single narrowband sampler with ultra-low sampling rate at each nodes to accomplish the wideband spectrum sensing.
