FECG Extraction Based On BSS Of Sparse Signal

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