Blind Separation of Nonstationary Sources Based on Spatial Time-Frequency Distributions
Blind source separation (BSS) based on spatial time-frequency distributions (STFDs) provides improved performance over blind source separation methods based on second-order statistics, when dealing with signals that are localized in the time-frequency ...

Blind Implicit Source Separation – A New Concept in BSS Theory
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

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

Denoising Using Blind Source Separation for Pyroelectric Sensors
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
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.

Abstract Simultaneous electroencephalography (EEG) recording during transcranial alternating current stimulation (tACS) is strongly contaminated by stimulation artifacts, limiting direct assessment of neural activity. Steady‐state visual evoked potentials (SSVEPs) provide frequency‐specific and phase‐locked responses, making them suitable for ...

Precoding-Based Blind Separation of MIMO FIR Mixtures
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

Abstract Objective The aim of this study was to retrospectively evaluate vision outcomes of dogs with primary angle closure glaucoma (PACG) that underwent Ahmed valve gonioimplantation (AVG) followed by lensectomy and endolaser cyclophotocoagulation (ECP) with or without bleb resection after AVG failure.
