(eng): In this paper, a number of important differences is discussed tht exist between independent component analysis with and without presence of an additive noise. It is shown that estimation of the mixing/demiging matrix should not be the main goal in the noisy case. Instead, usage of the signal-to-intarference ples noise criterion is suggested. Second, it is proposed to normalize norms of rows of the demixing matrix in the Monte Carlo experiments.
(cze): V tomto clanku je diskutovana rade existujicich rozdilu mezi slepou separaci linearni smesi signal bez pritomnosti a za pritomnosti aditivniho sumu. Je ukazano, ze odhad mixovaci nebo separujici matice by nemel byt hlavnim cilem separace, ale ze by jim melo byt dosazeny pomer uzitecneho signalu vuci interferenci a sumu. Dale je v clanku zduvodneno proc je vhodne v Monte Carlo simulacich normovat radky de-mixovaci (separacni) matice.
