ABSTRACT
The adaptive algorithms used for acoustic echo cancellation have to provide 1.high convergence rates and good tracking capabilities, since the acoustic environments imply very long and time-variant echo paths, 2.low misadjustments and robustness against background noise variations in double-talk. In this context, the affine projection algorithm and different versions of it are very attractive choices for acoustic echo cancellation
