Abstract

This paper deals with the extraction of the antepartum foetal electrocardiogram (ECG) from multilead cutaneous potential recordings, and the modelling of the transfer to the electrodes. We give an overview of a class of algebraic approaches, based on variants of the singular value decomposition (SVD): the concept, pros and cons of techniques relying on the ordinary SVD, quotient SVD and multilinear SVD are discussed.
