A Sparsity Preestimated Adaptive Matching Pursuit Algorithm

open access: yesJournal of Electrical and Computer Engineering, 2021
In the matching pursuit algorithm of compressed sensing, the traditional reconstruction algorithm needs to know the signal sparsity. The sparsity adaptive matching pursuit (SAMP) algorithm can adaptively approach the signal sparsity when the sparsity is ...

Expectation maximization based matching pursuit [PDF]

open access: yes2012 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2012
A novel expectation maximization based matching pursuit (EMMP) algorithm is presented. The method uses the measurements as the incomplete data and obtain the complete data which corresponds to the sparse solution using an iterative EM based framework. In standard greedy methods such as matching pursuit or orthogonal matching pursuit a selected atom can

Sparse Signal Recovery via Rescaled Matching Pursuit

open access: yesAxioms
We propose the Rescaled Matching Pursuit (RMP) algorithm to recover sparse signals in high-dimensional Euclidean spaces. The RMP algorithm has less computational complexity than other greedy-type algorithms, such as Orthogonal Matching Pursuit (OMP).

Sharp Convergence Rates for Matching Pursuit

open access: yesIEEE Transactions on Information Theory
We study the fundamental limits of matching pursuit, or the pure greedy algorithm, for approximating a target function $ f $ by a linear combination $f_n$ of $n$ elements from a dictionary. When the target function is contained in the variation space corresponding to the dictionary, many impressive works over the past few decades have obtained upper ...

Perturbed Orthogonal Matching Pursuit [PDF]

open access: yesIEEE Transactions on Signal Processing, 2013
Compressive Sensing theory details how a sparsely represented signal in a known basis can be reconstructed with an underdetermined linear measurement model. However, in reality there is a mismatch between the assumed and the actual bases due to factors such as discretization of the parameter space defining basis components, sampling jitter in A/D ...

Improved Weighted Matching Pursuit based Channel Estimation Algorithm

open access: yesGuangtongxin yanjiu, 2022
Compressive sensing based matching pursuit algorithm can estimate the channel state information of communication system with shorter pilot sequences. It has the advantages of lower computational complexity and less number of pilots.

AMP: ASSEMBLY MATCHING PURSUIT [PDF]

open access: yesBiocomputing 2013, 2012
Metagenomics, the study of the total genetic material isolated from a biological host, promises to reveal host-microbe or microbe-microbe interactions that may help to personalize medicine or improve agronomic practice. We introduce a method that discovers metagenomic units (MGUs) relevant for phenotype prediction through sequence-based dictionary ...
