METHOD AND DEVICE FOR BLIND EQUALIZING OF TRANSMISSION CHANNEL EFFECTS ON A DIGITAL SPEECH SIGNAL

摘要

the invention relates to a method anda device for blind equalizationeffects of a channel for the transmission of a signalto speak. the speech signal (s (t)} {s)converted into vectors cepstraux (1000)(c)} {n (i)). each of the vectors is cepstrauxsubject to adaptive filtering (1002).from a reference cepstre ({r n (1)}) (1001).representative of the long-term cepstre signalto speak, to create vectorscepstraux equalized ({c n (x)}))a speech signal equalized. application to the automatic recognition ofthe word.
