Non-invasive Extraction of Fetal Electrocardiogram and Maternal Electrocardiogram from Mixed Source Signal

Abstract

This paper is to bring in self-regulating methodology to obtain Fetal Electrocardiogram (FECG) and Maternal Electrocardiogram (MECG) from the mixed source signal. The Abdominal Electrocardiogram (AECG) is treated as an input signal to achieve the above-mentioned goal. FECG and MECG can be differentiated according to the power of a signal. FECG are weak signals as compared to that of MECG. But, FECG signals are engrossed in various other interference signals and thus its extraction has gained significance in the medical field. Various other methods and research work were done in this field. This paper is focused on non-invasive methods and by implementing independent component analysis. Various mathematical calculations are used in order to get accurate FECG signal. Then after ‘R’ peaks can be calculated and later fetal heart rate which will help to know the condition of the fetus in mother’s womb
