Abstract

A de-nosing approach is needed to eliminate the maternal heart sound and internal noise in the acquired fetal heart sound signal, but blind separation algorithm, as a conventional approach, does not perform well in the de-noising of fetal heart sound. Hence, a new fetal heart sound de-noising approach based on variational mode decomposition (VMD). Resampling is conducted for original signal on the basis of fetal heart sound signal characteristics, and then VMD is performed to select the signal components for independent component analysis with original signal, so as to obtain the de-noised fetal heart sound signal. As revealed in experimental results, this approach achieves better de-noising than the conventional methods. Hence, it is a favorable de-noising approach to reduce the noise mixed in the original fetal heart sound signal, so as to improve the computational accuracy of fetal heart rate and provide the prerequisite for effective fetal heart monitoring
