Powerline noise elimination in biomedical signals via blind source separation and wavelet analysis

The distortion of biomedical signals by powerline noise from recording biomedical devices has the potential to reduce the quality and convolute the interpretations of the data. Usually, powerline noise in biomedical recordings are extinguished via band-stop filters. However, due to the instability of biomedical signals, the distribution of signals filtered out may not be centered at 50/60 Hz. A...

Blind Source Separation: Application to biomedical signals

Blind Source Separation (BSS) is a prominent problem in signal processing. In the past few decades, it was applied to many fields, in which separation of compound signals, simultaneously observed by different sensors, is of interest. The problem can be considered as built-up of three physical elements: sources (also called transmitters), sensors (also called receivers) and communication channel...

Sparse coding blind source separation through Powerline

Without multiplexing, Powerline (PL) can support the concept of smart sensor web broadcasting of an N -sensors-to-single-owner (N -to-1) for household=stadium=mall=metro=city surveillance. In order to make the single user scenario feasible, the underdetermined blind source separation (BSS) problem x(k) = 〈a; s (k)〉+ n(k) has to be solved so that only inner product time series signal x(k) is kno...

Blind Source Separation: Biomedical applications

Blind source separation (BSS) refers to a wide class of methods in signal and image processing, which extract the underlying sources from a set of mixtures without almost any prior knowledge about the sources nor about the mixing process. In biomedical applications, BSS is used for the analysis of electroencephalogram (EEG), magenetoencephalogram (MEG) and electrocardiogram (ECG) signals and fu...

Blind source separation, wavelet denoising and discriminant analysis for EEG artefacts and noise cancelling

This paper proposes an automatic method for artefact removal and noise elimination from scalp electroencephalogram recordings (EEG). The method is based on blind source separation (BSS) and supervised classification and proposes a combination of classical and news features and classes to improve artefact elimination (ocular, high frequency muscle and ECG artefacts). The role of a supplementary ...
