Abstract

In the physiological process, the desired signal may not be directly measurable, and the investigator may not be able to determine the signal from measurable composite signals, such as the case of the fetus ECG (F-ECG). There is a problem in extracting the F_ECG signal from the composite maternal ECG signal obtained from the abdominal lead, because the Interference maternal ECG (M-ECG) is stronger than the fetus ECG signal. In this paper, the adaptive noise canceller is presented, to detect both the maternal and fetal ECG signals separately. The proposed scheme exhibits a good performance and the maternal and fetal ECG is successfully detected.
