Analysis of Multirate Adaptive Filters in Subbands.
Abstract
A subband adaptive filter architecture offers the possibility of performing the equivalent task of a fullband adaptive filter but with several key benefits. Results in the application of acoustic echo canceling demonstrate better convergence with fewer computations using a simulated acoustic echo path with white noise input. We are currently investigating performance using speech input. We are also looking at adaptive wavelet architectures for auto-regressive processes.
