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

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 ...

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.

Variational Bayesian algorithm for distributed compressive sensing [PDF]

open access: yes2015 IEEE International Conference on Communications (ICC), 2015
Distributed compressive sensing (DCS) concerns the reconstruction of multiple sensor signals with reduced numbers of measurements, which exploits both intra- and inter-signal correlations. In this paper, we propose a novel Bayesian DCS algorithm based on variational Bayesian inference.

Bayesian compressive sensing for primary user detection

open access: yesIET Signal Processing, 2016
In compressive sensing (CS)‐based spectrum sensing literature, most studies consider accurate reconstruction of the primary user signal rather than detection of the signal. Furthermore, possible absence of the signal is not taken into account while evaluating the spectrum sensing performance.
