File Information
Description

NLMS is one of the adaptive filter algorithms. In this file ,an experiment is made to identify a linear noisy system with the help of NLMS algorithm. The weights of the estimated system is nearly identical with the real one. Also , adaptive learning rate has been applied.A reference is used to write the algorithm.

Acknowledgements

Rls Algorithm Demo inspired this file.

Required Products Control System Toolbox
MATLAB release MATLAB 6.5 (R13)
Other requirements The sample data is created by the use of control system toolbox but it can easily created by any way else.

Wonderful example ... Easy code ... Now I understand the NLMS algorithm although I found it before tough.

plz send a NLMS algorithm demo for adaptive noise cancellation of voice and speech signal.

08 Feb 2005 prabodh sahoo

It is one of the efficient algorithm for noise cancellation.

Why don't you use adaptive filters with minimal MSE(mean square error)?
That's the reason, why is it poor :)

06 Nov 2003 loptos loptos

It's really poor...
