Abstract :
This paper introduces a new affine projection algorithm based on the dichotomous coordinate descent algorithm. A generalization for simplified Volterra filters is also made and its stability is improved by using a voice activity detector. The performance of the proposed algorithms for acoustic echo cancellation is assessed.
