Can independent component analysis (blind source separation) be used to extract antepartum fetal electrocardiograms from multilead cutaneous potential recordings?
Independent component analysis (blind source separation) is a promising signal processing tool for extracting fetal ECGs from non-invasive maternal cutaneous recordings.
In this paper, we propose the emerging technique of independent component analysis, also known as blind source separation, as an interesting tool for the extraction of the antepartum fetal electrocardiogram from multilead cutaneous potential recordings. The technique is illustrated by means of a real-life example.
