Process and the device for blind anabolism of influence of the transmission channel in the digital aural signal

摘要

(57) Abstract As for this invention, it regards the manner and the device in order blind anabolism the effect of the transmission channel in the digital aural signal. Aural signal ({s _n (t)}) sepusutorarubekutoru ({Cn (i)}) it is converted (1000). Each sepusutorarubekutoru is bet on adaptation filtering the access spectrum whichdisplays long-term sepusutoramu of the aural signal in order is displayed anabolism to be generated the anabolism aural signal ({Rn (i)}) of on the basis, (1002). This invention is applicable in automatic speech recognition.
