Application of variations of the LMS adaptive filter for voice communications with control system

Abstract

This paper describes a proposed method for optimal adjustment parameters of variations of the LMS adaptive filter in the application of suppression of the additive noise from the speech signal. Selected variation of the LMS adaptive noise canceller is implemented on the TMS320C6713 DSK. This practical realization was used in a voice communication with a control system for controlling of operating – technical functions in buildings.
