Abstract
BACKGROUND: Fetal electrocardiogram (FECG) is an objective index of the activities of fetal cardiac electrophysiology, but the Department of
obtained FECG is interferenced by maternal ECG. How to extract the FECG quickly and effectively has e an important Medical Information

OBJECTIVE: To separate FECG signal from the mother's ECG more rapidly and accurately by using improved fast (ICA) 610065, Sichuan
algorithm in order to achieve a more accurate FECG examination from fetal health purposes. Province, China
METHORDS: Relaxation factor and the closeness measure function were added to fast ICA, the differences of speed and
