Selection of an optimal adaptive filter for speech signal noise cancellation using C6455 DSP

Autor: Liudas Stašionis, Arturas Serackis

This article discusses the implementation of the various adaptive filters for the filtering of the noisy speech signal, whose spectrum overlaps or is close to the information signal. Three types of adaptive filters are compared: LMS, NLMS and RLS. Th
