Adaptive Sensing for Sparse Signal Recovery [PDF]

open access: yes2009 IEEE 13th Digital Signal Processing Workshop and 5th IEEE Signal Processing Education Workshop, 2009
The theory of compressed sensing shows that sparse signals in high-dimensional spaces can be recovered from a relatively small number of samples in the form of random projections. However, in severely resource-constrained settings even CS techniques may fail, and thus, a less aggressive goal of partial signal recovery is reasonable.

Sparse signal recovery from sparsely corrupted measurements [PDF]

open access: yes2011 IEEE International Symposium on Information Theory Proceedings, 2011
We investigate the recovery of signals exhibiting a sparse representation in a general (i.e., possibly redundant or incomplete) dictionary that are corrupted by additive noise admitting a sparse representation in another general dictionary. This setup covers a wide range of applications, such as image inpainting, super-resolution, signal separation ...

Multi-sparse signal recovery for compressive sensing [PDF]

open access: yes2012 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2012
Signal recovery is one of the key techniques of Compressive sensing (CS). It reconstructs the original signal from the linear sub-Nyquist measurements. Classical methods exploit the sparsity in one domain to formulate the L0 norm optimization. Recent investigation shows that some signals are sparse in multiple domains.

Sparse Analysis Recovery via Iterative Cosupport Detection Estimation

open access: yesIEEE Access, 2021
Cosparse analysis model (CAM) provides a new signal processing paradigm for recovering cosparse signals with respect to a given analysis operator from the undersampled linear measurements in the context of emerging theory of compressed sensing (CS).

Space alternating variational estimation based sparse Bayesian learning for complex‐value sparse signal recovery using adaptive Laplace priors

open access: yesIET Signal Processing, 2023
Due to its self‐regularising nature and its ability to quantify uncertainty, the Bayesian approach has achieved excellent recovery performance across a wide range of sparse signal recovery applications.

A Multi-Source Separation Approach Based on DOA Cue and DNN

open access: yesApplied Sciences, 2022
Multiple sound source separation in a reverberant environment has become popular in recent years. To improve the quality of the separated signal in a reverberant environment, a separation method based on a DOA cue and a deep neural network (DNN) is ...

Sparse signal reconstruction by swarm intelligence algorithms

open access: yesEngineering Science and Technology, an International Journal, 2021
This study introduces a new technique for sparse signal reconstruction. In general, there are two classes of algorithms in the recovery of sparse signals: greedy approaches and l1-minimization methods. The proposed method employs swarm intelligence based
