A fetal ECG contains important indications about the health conditions of fetus, and could become a diagnostic tool of particular importance. One way to obtain the fetal ECG is by recording it on the mother's abdomen. The recording is complicated by the existence of a strong maternal ECG and random contamination due to non cardiac sources. This research gives a study of separating the fetal ECG from the strong maternal trace and to separate the fetal ECG from the noise.
