ECHOLÖSCHUNG

摘要

An echo cancellation device ( 1 ) comprises a first adaptive filter ( 13 ) for producing a first echo cancellation signal (y₁), a second adaptive filter ( 15 ) for producing a second echo cancellation signal (y₂), and a post-processor ( 18 ) for suppressing any remaining echo. The first adaptive filter ( 13 ) and the second adaptive filter ( 15 ) are designed for canceling a first (e.g. direct) part of the echo impulse response and a second (e.g. diffuse) part of the echo impulse response respectively. The device ( 1 ) may be utilized in a mobile telephone.
