This article is intended to be used by researchers a practical guide to

NI-FECG signal processing, in the context of the above issues. It reviews

recent advances in NI-FECG research including: publicly available

databases, NI-FECG extraction techniques for foetal heart rate uation

and morphological analysis, NI-FECG simulators and the methodology

and statistics for assessing the performance of the extraction algorithms.
