| Abstract: | A new method of blind signal separation was provided to achieve FECG (Fetal ECG) detection. The lead system characteristic for pregnant ECG signal was studied at first, then an on line FECG monitoring system was designed. Because the on line learning algorithm of blind signal separation was used, FECG signal can be detected in real time. Some experimental results proved this monitoring system to be an efficient one. |
