Abstract :
Independent component analysis (ICA) is an effective source separation method, and has been widely used in fetal signal detection from abdominal maternal electrocardiogram (ECG) and magnetocardiography (MCG). One difficulty with the application of ICA is to determine the character information of independent components. A method, based on a simple statistical parameter-kurtosis, is proposed in this paper to solve the problem. It has been successfully applied to remove the maternal signal and the noise from the raw fetal MCG (fMCG) data of a 28-week pregnant woman through a 5-channel fMCG detector. The method offers potential applications for online processing of fMCG using ICA.
