3. 2. Low-Complexity Algorithms for Echo Cancellation in Audio Conferencing Systems

   Författare :Christian Schüldt; Blekinge Tekniska Högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustic echo cancellation; Adaptive filtering; Two-path; Double-talk detection;

   Sammanfattning : Ever since the birth of the telephony system, the problem with echoes, arising from impedance mismatch in 2/4-wire hybrids, or acoustic echoes where a loudspeaker signal is picked up by a closely located microphone, has been ever present. The removal of these echoes is crucial in order to achieve an acceptable audio quality for conversation. LÄS MER
