Blind separation of maternal and fetal ECG recordings using adaptive sparse representations

Blind separation of maternal and fetal ECG recordings using adaptive sparse representations
Blind separation of maternal and fetal ECG recordings using adaptive sparse representations
In this paper we present a method to blindly separate maternal and fetal ECG signals using recordings made from the maternal abdomen. The method is general and is able to separate the signals using any number of recording electrodes, including the difficult case of single channel blind source separation. The approach is based on the assumption that the signals admit a sparse and shift-invariant representation. Adaptation of the representation then leads to the emergence of the PQRST complexes of the maternal and the fetal heart for each electrode so that we can separate the individual sources by reconstructing the signal using only a single PQRST complex.

Abstract

In this paper we present a method to blindly separate maternal and fetal ECG signals using recordings made from the maternal abdomen. The method is general and is able to separate the signals using any number of recording electrodes, including the difficult case of single channel blind source separation. The approach is based on the assumption that the signals admit a sparse and shift-invariant representation. Adaptation of the representation then leads to the emergence of the PQRST complexes of the maternal and the fetal heart for each electrode so that we can separate the individual sources by reconstructing the signal using only a single PQRST complex.
