Abstract
The lattice-structured adaptive noise canceller has been studied: a brief formula about the relation of its misadjustment to the step size and the number of stages has been found theoretically and checked experimentally, showing that the misadjustment increases exponentially with the number of stages, an optimized step size has been applied to multi-stage lattice filter, with drastic reduction in convergence time.
