Abstract :
A new method for foetal ECG separation based on temporally constrained independent component analysis (ICA) is proposed. The maternal beat positions were regarded as a priori information and by applying constrained ICA, a maternal dominant signal could be extracted. Finally, a foetal ECG signal was obtained by the subtraction of this from a specific channel signal.
