File Information
Description

This model uses the NLMS adaptive filtering algorithm to suppress additive noise. It does not require a reference noise signal. However, the noise should be such that the auto-correlation of the noise be close to zero for some lag greater than a certain number. This model implements the NLMS algorithm using Embedded MATLAB.

There are two version of the model: One uses sample-based signals and the other uses frame-based signals.

Required Products DSP System Toolbox
