intelligent technique of canceling maternal ecg in fecg extraction

in this paper, we propose a technique of artificial intelligence called adaptive neuro fuzzy inference system (anfis) for canceling maternal electrocardiogram (mecg) in fetal electrocardiogram extraction (fecg).this technique is used to estimate the mecg present in the abdominal signal of a pregnant woman. the fecg is then extracted by subtracting the estimated mecg from the abdominal signal. performance of the proposed method in terms of mean square error, signal to noise ratio is compared with neural network. our results show that this method is a simple and powerful means for the extraction of fecg.
