Beamformers for sparse recovery

open access: yes2013 IEEE International Conference on Acoustics, Speech and Signal Processing, 2013
In sparse recovery from measurement data a common approach is to use greedy pursuit reconstruction algorithms. Most of these algorithms have a correlation filter for detecting active components in the sparse data. In this paper, we show how modifications can be made for the greedy pursuit algorithms so that they use beamformers instead of the standard ...

Scaling Law for Recovering the Sparsest Element in a Subspace [PDF]

open access: yes, 2014
We address the problem of recovering a sparse $n$-vector within a given subspace. This problem is a subtask of some approaches to dictionary learning and sparse principal component analysis.

An Armijo-Type Hard Thresholding Algorithm for Joint Sparse Recovery

open access: yesIEEE Access, 2021
Joint sparse recovery (JSR) in compressed sensing simultaneously recovers sparse signals with a common sparsity structure from their multiple measurement vectors obtained through a common sensing matrix.

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 ...
