Extraction of fetal ECG from maternal ECG

Biomedical signals taken from body surface by non-invasive methods include problems such as noise and mixing with other physiological signals. These problems also appear evidently during the extraction of fetal ECG´s. Therefore, the fetal EKG signal is contaminated by maternal ECG signal and noise. In this study, the purpose is to determine the best algorithm for fetal ECG extraction by using two different blind source separation based method. To determine the best algorithm, detection of fetal heart rate and signal-interface ratio criterion were used.
