Noise Suppressor Using Adaptive Filters

This model uses the NLMS adaptive filtering algorithm to suppress noise.

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.
