Abstract: The present study aims to validate a new approach for blind source separation of fetal electrocardiogram signal FECG and maternal electrocardiogram signal MECG when given only a single channel recording. Most studies have only focused on statistical methods which impose several conditions on the sources and this is not always obvious. The proposed method by combining continuous wavelet transform CWT and non-negative matrix factorization NMF, allows the extraction of the FECG signal with a greater characterization of the QRS complex. This technique can be illustrated by means of a real-life example.
