ABSTRACT
Fetal electrocardiogram (FECG) extraction is an interesting and challenging problem in biomedical engineering. The antepartum FECG is usually obtained through skin electrodes attached to the mother’s body [89]. Unfortunately, the desired fetal heartbeat signals appear at the electrode output buried in an additive mixture of undesired disturbances, such as the mother’s heartbeat signal with extremely high amplitude, the noise caused by mother’s respiration, and electronic equipment. Appropriate signal processing techniques are required to recover the wanted FECG components from the corrupted potential recordings.
