基于盲信号分离的胎儿心电提取

FECG DETECTION BASED ON BLIND SIGNAL SEPARATION

本文提出了用盲信号分离提取胎儿心电的方法。首先研究了孕妇心电导联的特性 ,然后在此基础上设计了一个胎儿心电实时监护系统。由于使用了实时的盲信号分离算法 ,胎儿心电可以实时的被提取。

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.
