Abstract

It is known that extraction of fetal electrocardiogram (FECG) from maternal skin electrode measurements has vital significance for fetal monitoring. The fetal and maternal signals have their own specific temporal or statistical structures; In view of this fact our paper introduces a new semi-blind method of extracting fetal electrocardiogram as the following: the maternal signal is firstly removed from mixture signals by using its periodic property. Then the fetus signal is recovered according to its kurtosis information. Simulation results show the performance of the proposed extraction algorithm is getting better.
