NLMS algorithm demo with adaptive learning rate.

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	The author wishes to acknowledge the following in the creation of this submission: RLS Algorithm Demo
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.

06 Nov 2003	loptos loptos	It's really poor...
06 Nov 2003	loptos loptos	Why don't you use adaptive filters with minimal MSE(mean square error)? That's the reason, why is it poor :)

27 Nov 2006	eu é que sei!!	è pa!! our teacher has said that this prog is such a bullshit!! u have to improve this m file!! hugs and good work!!
27 Nov 2006	Boda, John	Great job for a useless student. Now you can do better. It is a lot of mistakes, so let's go work kid.
28 Nov 2006	John Kelly	Excellent !
03 Dec 2006	Nora Spahiu	Good work pal
28 Dec 2006	Rashid Haloli	Wonderful example ... Easy code ... Now I understand the NLMS algorithm although I found it before tough.
03 Jan 2007	Vishnuvenkatesh Dhage	novice user can easily understood the code
27 Mar 2007	Hao Yanchun	You do a good job!Thank you!
