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

Robust Automatic Modulation Classification in Low Signal to Noise Ratio
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.

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

The Application of Contrast-Enhanced 3D-STIR-VISTA MR Imaging of the Brachial Plexus
Objective: To introduce contrast-enhanced 3D-STIR-VISTA sequence that would improve the image quality for the brachial plexus imaging and enhance the contrast between the brachial plexus and surrounding tissues.

Pitch-scaled estimation of simultaneous voiced and turbulence-noise components in speech
Almost all speech contains simultaneous contributions from more than one acoustic source within the speaker's vocal tract. In this paper, we propose a method -- the pitch-scaled harmonic filter (PSHF) -- which aims to separate the voiced and turbulence ...

Adaptive Signal-to-Noise Ratio Indicator for Wearable Bioimpedance Monitoring
Bioimpedance monitoring is an increasingly important non-invasive technique for assessing physiological parameters such as body composition, hydration levels, heart rate, and breathing.

With the introduction of information theory in the middle of the 20th century, the concept of noise came to be contrasted with signal. The exhibition Noise to Signal mainly consists of two projects that highlight the relative nature of these terms.

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

Signal to Noise Ratio of a Coded Slit Hyperspectral Sensor
In recent years, a wide range of hyperspectral imaging systems using coded apertures have been proposed. Many implement compressive sensing to achieve faster acquisition of a hyperspectral data cube, but it is also potentially beneficial to use coded ...
