Extraction of Foetal Contribution to ECG Recordings Using Cyclostationarity-Based Source Separation Method

Résumé

In this paper we propose a cyclostationary approach to the problem of the foetal electrocardiogram (FECG) extraction from a set of cutaneous potential recordings of an expectant mother. We adopted a semi-blind source separation (BSS) method for which the only necessary prior knowledge is that of the fundamental cyclic frequency of the cyclostationary process to be estimated. Using this technique, the estimated cyclostationary FECG source of interest is found to be free from any interferences with the mother's ECG (MECG) signal. Experimental results and perspectives for future research conclude this paper.
