Abstract
In this paper we apply Independent Component Analysis to magnetocardiographic data recorded from the abdomen of pregnant women. In particular, we include a dimensionality reduction in the ’Cumulant Based Iterative Inversion’ algorithm to achieve a ’signal subspace’ subdivision, which enhances the algorithm’s efficacy in resolving the signals of interest from the recorded traces. Our results show that the proposed two-step procedure is a powerful means for the extraction of the cardiac signals from the background noise and for a sharp separation of the baby’s heart from the mother’s.
