Abstract

We propose an extension of independent component analysis when applied for fetal ECG extraction. Before using the classical ICA method, we multiply the number of measured signals using the technique of delays (each signal channel delayed by a proper time interval is regarded as a new measured signal). After this duplication of the measured signal channels, the classical JADE algorithm is applied to perform blind separation of independent source signals. Then we use a simple algorithm to select the estimated source signal that contains the fetal ECG of the best quality. We compare the results obtained using the classical ICA and the approach proposed. The experiments performed on 4-channel maternal abdominal ECG signals confirm the superior performance of this approach.
