SARMIENTO-ALVAREZ, Luis Omar; MILLET-ROIG, José  e  GONZALEZ-SALVADOR, Alberto. Fetal electrocardiogram extraction using hybrid BSS technique: COMBI and MULTICOMBI algorithms. Iteckne [online]. 2014, vol.11, n.2, pp.121-128. ISSN 1692-1798.

In this paper, we use two algorithms for obtaining fetal ECG from abdominal ECG. The algorithms are MULTICOMBI and COMBI, which are a combination of EFICA and WASOBI algorithms. The performance of the algorithms COMBI, MULTICOMBI, WASOBI, EFICA and traditional JADE algorithm are compared. A semi synthetic database and two actual databases are used to compare the performance of algorithms using as parameter the signal to error ratio SER. It is found that the COMBI and MULTICOMBI algorithms show better performance than the JADE, EFICA and WASOBI algorithms.
