Abstract：

Because　the　difference　among　mother　electrocardiogram(　MECG)＇attractors,　fetal　ECG　(FECG)＇s　and　other　noise＇s,　a　local　linear　projection　technique　is　presented　for　extraction　FECG　from　an　abdominal　ECG　recording　of　a　pregnant　woman.　The　basic　idea　of　the　technique　is　the　identification　of　the　hyperplane　containing　the　FECG　signal　and　projection　the　noisy　data　onto　this　manifold.　Visual　test　results　obtained　from　mimic　and　real　ECG　signals　show　that　the　proposed　algorithm　is　capable　of　reliably　extracting　the　FECG　from　one　lead　only.　Also　its　performance　is　compared　to　Widrow＇s　multi-reference　adaptive　filtering　method.　The　experimental　outcome　demonstrates　the　power　of　the　technique　in　this　important　biomedical　application.　©　2008　IEEE.
