A study of fetal ECG separation from small channel abdominal ECGs using ICA

Algorithm to extract fetal ECGs with a few channel data gathered from the wearable fetal ECG module was proposed. By adding fake noise signals to two-channel abdominal ECGs which eliminated noise using wavelet transform, ICA was applied. As a result, maternal ECGs were gained that excluded fetal ECGs. Along with the signals, the application of adaptive filter extracted fetal ECGs from ECGs signals that fetal and maternal ECGs existed together.
