Abstract
The detection of the fetal QRS complex from one composite signal recorded from the abdominal area is a challenging problem for both the biomedical and signal processing communities. In this work, in contrast to the classical approach using Singular Value Decomposition (SVD) based on the analysis of the singular value ratio, we present a new approach using optimal SVD based on difference spectrum energy to detect the QRS complexes of the fetus cardiac activity, also the Undecimated Wavelet Transform (UWT) was used for noise filtering and to determine peaks locations. The result of the R peaks performance measure is calculated for the two approaches. This method is advantageous since it is based on the analysis of one abdominal signal, and it is validated in both the synthetic and real signals.
