摘要/Abstract：
The fetal heart rate is vital for monitoring fetal well-being. Fetal heart rate monitoring based on acoustic techniques is passive and noninvasive. In this work, a fetal heart rate monitoring system based on phonocardiographic method is proposed. A portable low-power stethoscope is customized which meets the need for sensitivity in the monitoring. A noise cancellation method and adaptive matching method are applied to extract the fetal heart rate effectively. Clinical trials are carried out on pregnant women, and the comparison of fetal heart rates given by the proposed system with those given by the Doppler monitor is given to show the accuracy.
