Energy Efficient GNSS Signal Acquisition Using Singular Value Decomposition (SVD) [PDF]

open access: yesSensors, 2018
A significant challenge in global navigation satellite system (GNSS) signal processing is a requirement for a very high sampling rate. The recently-emerging compressed sensing (CS) theory makes processing GNSS signals at a low sampling rate possible if ...

Componentwise Perturbation Analysis of the Singular Value Decomposition of a Matrix

open access: yesApplied Sciences
A rigorous perturbation analysis is presented for the singular value decomposition (SVD) of a real matrix with full column rank. It is proved that the SVD perturbation problem is well posed only when the singular values are distinct.

Truncated singular value decomposition in ripped photo recovery [PDF]

open access: yesITM Web of Conferences, 2021
Singular value decomposition (SVD) is one of the most useful matrix decompositions in linear algebra. Here, a novel application of SVD in recovering ripped photos was exploited. Recovery was done by applying truncated SVD iteratively.

A Partial Discharge Pulse Extraction and Denoising Technology Based on Random Singular Value Decomposition

open access: yesZhongguo dianli, 2021
Partial discharge signals are prone to missed detection under low signal-to-noise ratios, and the traditional singular value decomposition algorithm requires massive calculations when extracting partial discharge pulses.

Partial Discharge Signal Extraction Method Based on EDSSV and Low Rank RBF Neural Network

open access: yesIEEE Access, 2021
The detection process of partial discharge (PD) ultra-high frequency (UHF) signal is easily affected by white noise and periodic narrowband noise, which hinder the fault diagnosis of high-voltage electrical appliances.

Two-Channel Information Fusion Weak Signal Detection Based on Correntropy Method

open access: yesApplied Sciences, 2022
In recent years, as a simple and effective method of noise reduction, singular value decomposition (SVD) has been widely concerned and applied. The idea of SVD for denoising is mainly to remove singular components (SCs) with small singular value (SV ...
