The　electrocardiograph　signal　presents　the　sparseness.　In　this　paper,　a　new　method　of　extracting　the　Fetal　Electrocardiograph　(FECG)　is　proposed,　which　uses　the　Blind　Source　Separation(BSS)　of　Sparse　Signal.　Both　the　Wavelet　Analysis　method　and　a　new　scheme　named　Vanish　Circle　are　also　involved　in　order　to　avoid　the　influence　on　the　signal　separation,　because　the　ECG　signals　are　not　completed　sparse　signals.　Some　experiments　show　that　the　new　method　is　effective.
