Stationary Points of a Kurtosis Maximization Criterion for Noisy Blind Source Extraction

IEEE Access, 2017
Blind source extraction (BSE) is often posed as the maximization of a statistical criterion under a unitary constraint. This paper addresses the convergence problem of a kurtosis-based criterion in the presence of noise.

Blind Implicit Source Separation – A New Concept in BSS Theory

, 2012
The Blind Source Separation (BSS) problem was first introduced (Herault et al., 1985; Jutten & Herault, 1988) in the context of biological problems (Ans et al., 1983; Herault & Ans, 1984) with the aim of being able to separate a set of signals generated by the central nervous system. A few years later, several methods based on BSS were applied to other

Denoising Using Blind Source Separation for Pyroelectric Sensors

EURASIP Journal on Advances in Signal Processing, 2001
This paper deals with a process of denoising based on a Blind Source Separation (BSS) method. This technique is inserted in an experimental device of nondestructive testing. Its excitation is a laser beam and its detectors are pyroelectric sensors.

Short-Sampled Blind Source Separation of Rotating Machinery Signals Based on Spectrum Correction

Shock and Vibration, 2016
Nowadays, the existing blind source separation (BSS) algorithms in rotating machinery fault diagnosis can hardly meet the demand of fast response, high stability, and low complexity simultaneously.

Pathological classification of Fuchs endothelial corneal dystrophy into several types and their relationships with CTG18.1 expansion repeats

The Journal of Pathology, EarlyView.
Abstract Late‐onset Fuchs endothelial corneal dystrophy (FECD) is the most common primary disease of the corneal endothelium and the leading indication for corneal transplantation in Western countries. It is characterized by progressive accumulation, over two to three decades, of extracellular matrix (ECM) components in Descemet's membrane (DM ...

Precoding-Based Blind Separation of MIMO FIR Mixtures

IEEE Access, 2017
This paper focuses on the problem of blind separation of sources mixed by multi-input multi-output finite impulse response channels, which is also called convolutive blind source separation (BSS) in short. This problem has been intensively studied in the

A Novel Improved Threshold Adaptive Forgetting Variable Step Size Blind Separation Model for Weak Signal Detection

Shock and Vibration, 2022
The online blind source separation (BSS) is seriously disturbed by strong noise when extracting weak signals and has the defects that it cannot both give consideration to convergence speed and steady-state error.

Single-channel blind source separation of underwater acoustic signals using improved NMF and FastICA

Frontiers in Marine Science, 2023
When automatic monitoring buoys receive mixed acoustic signals from multiple underwater acoustic targets, the statistical blind source separation (BSS) task is used to separate the signals and identify vessel features, which is overly complex and needs ...
