Maternal electrocardiogram (MECG) suppression is a critical procedure to estimate fetal heart rate (FHR). The impulse noises in maternal abdomen signals (ADS) include electromyographic interference (EMGI) and fetal R waves, which deteriorate FHR estimation in MECG suppression. In this paper, we introduce the M-estimation methods, a more robust methodology, to extract pure MECG in impulse noises. In order to evaluate the performance of M-estimation methods, two innovative quantitative performance metrics, namely loss degree of fetal R wave and sensitivity of initial value, are proposed. Numerical results show that: (1) FHR estimation using M-estimation methods is more accurate than least square method (LSM) in impulse noises; (2) the robust performance of Fair is better than that of Cauchy in low SNR; (3) the robust performance of Cauchy is superior to that of Fair in high SNR.
