Residual Echo Suppression Considering Harmonic Distortion and Temporal Correlation
Applied Sciences, 2020 In acoustic echo cancellation, a certain level of residual echo resides in the output of the linear echo canceller because of the nonlinearity of the power amplifier, loudspeaker, and acoustic transfer function in addition to the estimation error of the ...

Echo Cancellation : the generalized likelihood ratio test for double-talk vs. channel change [PDF]
, 2009 Echo cancellers are required in both electrical (impedance mismatch) and acoustic (speaker-microphone coupling) applications. One of the main design problems is the control logic for adaptation.

A codesign experiment in acoustic echo cancellation: GMDFα
Proceedings of 9th International Symposium on Systems Synthesis, 1997 Continuous advances in processor and ASIC technologies enable the integration of more and more complex embedded systems. Embedded systems have become commonplace in recent years. Since their implementations generally require the use of heterogeneous resources (e.g., processor cores, ASICs) in one system with hard design constraints, the importance of ...

Subband Affine Projection Algorithm for Acoustic Echo Cancellation System
EURASIP Journal on Advances in Signal Processing, 2007 We present a new subband affine projection (SAP) algorithm for the adaptive acoustic echo cancellation with long echo path delay. Generally, the acoustic echo canceller suffers from the long echo path and large computational complexity.
