Wideband Spectrum Sensing: A Bayesian Compressive Sensing Approach [PDF]

open access: yesSensors, 2018
Sensing the wideband spectrum is an important process for next-generation wireless communication systems. Spectrum sensing primarily aims at detecting unused spectrum holes over wide frequency bands so that secondary users can use them to meet their ...

Resolution Enhancement for Millimeter-Wave Radar ROI Image with Bayesian Compressive Sensing [PDF]

open access: yesSensors, 2022
For millimeter-wave (MMW) imaging security systems, the image resolution promisingly determines the performance of suspicious target detection and recognition. Conventional synthetic aperture radar (SAR) imaging algorithms only provide limited resolution

Bayesian Compressive Sensing of Sparse Signals with Unknown Clustering Patterns [PDF]

open access: yesEntropy, 2019
We consider the sparse recovery problem of signals with an unknown clustering pattern in the context of multiple measurement vectors (MMVs) using the compressive sensing (CS) technique. For many MMVs in practice, the solution matrix exhibits some sort of

Multi-Frequency GPR Microwave Imaging of Sparse Targets through a Multi-Task Bayesian Compressive Sensing Approach [PDF]

open access: yesJournal of Imaging, 2021
An innovative inverse scattering (IS) method is proposed for the quantitative imaging of pixel-sparse scatterers buried within a lossy half-space. On the one hand, such an approach leverages on the wide-band nature of ground penetrating radar (GPR) data ...

Bayesian Compressive Sensing Based Optimized Node Selection Scheme in Underwater Sensor Networks [PDF]

open access: yesSensors, 2018
Information acquisition in underwater sensor networks is usually limited by energy and bandwidth. Fortunately, the received signal can be represented sparsely on some basis. Therefore, a compressed sensing method can be used to collect the information by

A Sound Source Identification Algorithm Based on Bayesian Compressive Sensing and Equivalent Source Method [PDF]

open access: yesSensors, 2020
Near-field acoustic holography (NAH) based on equivalent source method (ESM) is an effective method for identifying sound sources. Conventional ESM focuses on relatively low frequencies and cannot provide a satisfactory solution at high frequencies.

Data-adaptive pattern-coupled Bayesian compressive sensing for sparse sound field reconstruction [PDF]

open access: yesScientific Reports
Pattern-coupled Bayesian compressive sensing shows great potential in sound field reconstruction by leveraging structural sparsity, but its fixed coupling patterns for sparsity hyperparameters limit adaptability to non-uniform correlation distributions ...
