Abstract :
Fetal electrocardiogram (FECG) extraction is an important issue in biomedical signal processing. In this paper, we develop an
objective function for extraction of FECG. The objective function is based on the non-Gaussianity and the temporal structure of
source signals. Maximizing the objective function, we can extract the desired FECG. Combining with the solution vector obtained
by maximizing the objective function, we further improve the accuracy of the extracted FECG. In addition, the feasibility of the
innovative methods is analyzed by mathematical derivation theoretically and the efficiency of the proposed approaches is illustrated
with the computer simulations experimentally.
