Acoustic Echo Canceller Using the Error Coded Affine Projection Algorithm

J. G. Avalos-Ochoa, F. A. Serrano-Orozco, and G. Avalos-Arzate
Abstract—Adaptive algorithms used in acoustic echo cancellers (AEC) must present high convergence speed and low misadjustment, therefore algorithms like the affine projection (APA) are frequently used, nevertheless its high computational complexity could be a problem for hardware implementations. In this paper, we present an acoustic echo canceller using the Error Coded Affine Projection Algorithm, which is a modification that assigns a code to the error and establishes a threshold to update the filter coefficients, in such way the coefficient update is not performed during each iteration. Results show the efficiency of the algorithm in terms of good convergence behavior, final misadjustment and a considerable reduced number of updates, making this a great option for AEC implementations.

Index Terms—Acoustic echo canceller, Adaptive filters, Affine projection algorithm, Computational cost.
