Block-Sparse Fast Recursive Approximated Memory Improved Proportionate Affine Projection Algorithm

Document Thumbnail

A new approximated memory improved proportionate affine projection algorithm for block sparse echo cancellation is proposed. This contribution presents a fast recursive implementation combined with the use of dichotomous coordinate descent iterations. It is shown that the proposed algorithm has superior convergence speed and tracking abilities for echo path changes in the context of acoustic and network echo cancellation applications. Also it is proved that these achievements are obtained while having a reduced numerical complexity than competing algorithms.
