A method for extracting fecg based on ICA algorithm

摘要

Inorder to extract the purer fetal ECG accurately, a BSS method based on higher-order statistics is contrasted with a significant classical technique for FECG extraction. The FastICA algorithm and Infomax ICA algorithm are used for FECG extraction. They were applied to multichannel ECG recording obtained from a pregnant woman. It was observed that both algorithms were able to extract the fetal ECG. But the experiment outcomes demonstrate that the better performance is Fast-ICA algorithm in the biomedical application. This method has been proved to be able to extract the desired fetal heart beat signal from the composite abdominal signal.
