Spatio-Temporal FIR Filter for Fetal ECG Extraction
Keywords:
Fetal electrocardiogram, maternal ECG suppression, spatio-temporal filtering, generalized eigendecomposition.Abstract
In this paper we propose to apply spatio-temporal filtering to fetal ECG extraction from the multichannel maternal abdominal bioelectric signals. The method performs weighted addition of the assumed number of time samples of the respective measured signal channels. The filter weights are calculated during the learning phase of the method. After this learning phase, the filter operation is very simple, similar to usual filtering, nevertheless extraordinarily effective. Our experiments show that it can simultaneously accomplish maternal ECG suppression and fetal QRS complexes enhancement for their detection. The detection tests are performed to show the method influence on this crucial
operation.
