| Outline of Final Research Achievements |
In this study, we developed a method for removing or separation of additive and convolutive artifacts artifact from multi-dimensional biosignals with independent vector analysis. We applied the method to extract fetal electrocardiogram from maternal abdomen as a test of our proposed method. As a results, the proposed method showed better performance rather than the conventional independent component analysis method. In addition, we developed a method for estimating a distribution of fetal cardiac potential which was observed on the maternal abdomen. The distributions are of help in order to find electrodes’ coordination which has better performance on the maternal abdomen.
