Fetal Electrocardiogram (FECG) can provide important clinical information for the assessment of fetal well-being. However, the extraction of FECG from the maternal abdominal wall remains an open problem due to various kinds of interferences and noises, where the maternal Electrocardiogram (MECG) is the dominant source of interference. In this study, a novel FECG extraction framework by combining single-channel singular value decomposition (S-SVD) and cyclostationarity-based blind source separation (C-BSS) is proposed. First, the MECG signal as the principal quasi periodic component is extracted with S-SVD algorithm from a single channel recording. Then, the FECG signal is preliminarily acquired by subtracting the MECG from the corresponding abdominal MECG (AMECG) recording. Finally, the FECG is further extracted by C-BSS, where a new cost function is constructed with high order cumulant and second order cyclic frequency. Results show the proposed method improves the accuracy of extracted FECG in comparison with the traditional BSS algorithm like independent component analysis (ICA).
