Artifact reduction in multichannel pervasive EEG using hybrid WPT-ICA and WPT-EMD signal decomposition techniques [PDF]

, 2014
In order to reduce the muscle artifacts in multi-channel pervasive Electroencephalogram (EEG) signals, we here propose and compare two hybrid algorithms by combining the concept of wavelet packet transform (WPT), empirical mode decomposition (EMD) and ...

iCap: New method for noise reduction in electroencephalography (EEG) signals

مجلة جامعة دمشق للعلوم الهندسية, 2022
Electroencephalographic (EEG) signal’s importance increases as the neurotechnology research and industry accelerate. Therefore, it is crucial to acquire noise-free signals by maximising the signal-to-noise ratio (SNR). Many methods are followed to clean

Remote Sensing Low Signal-to-Noise-Ratio Target Detection Enhancement

Sensors, 2023
In real-time remote sensing application, frames of data are continuously flowing into the processing system. The capability of detecting objects of interest and tracking them as they move is crucial to many critical surveillance and monitoring missions ...

Adaptive processing with signal contaminated training samples [PDF]

, 2013
We consider the adaptive beamforming or adaptive detection problem in the case of signal contaminated training samples, i.e., when the latter may contain a signal-like component.

Robust Automatic Modulation Classification in Low Signal to Noise Ratio

IEEE Access, 2023
In a non-cooperative communication environment, automatic modulation classification (AMC) is an essential technology for analyzing signals and classifying different kinds of signal modulation before they are demodulated.

Attention-dependent modulation of cortical taste circuits revealed by granger causality with signal-dependent noise [PDF]

, 2013
We show, for the first time, that in cortical areas, for example the insular, orbitofrontal, and lateral prefrontal cortex, there is signal-dependent noise in the fMRI blood-oxygen level dependent (BOLD) time series, with the variance of the noise ...

Phrases in noise test (PINT) Brazil: effectiveness of the test in children with hearing loss

Brazilian Journal of Otorhinolaryngology, 2021
Introduction: One of the main implications of hearing impairment is the difficulty in perceiving speech sounds, especially in noisy environments. Thus, the frequency-modulated system is considered an important educational tool for children with hearing ...

Compression by Noise Equalization [PDF]

, 2013
For any relation of the noise variance with the gray value, a nonlinear transform h(g) can be applied so that the variance of the transformed signal h is constant.
