RLS Algorithm Demo

29 May 2002 (Updated 31 Oct 2003)

No BSD License

A system identification by the usage of the RLS algorithm.

File Information
Description	RLS is one of the great adaptive filter algorithms. In this file ,an experiment is made to identify a linear noisy system with the help of RLS algorithm. The weights of the estimated system is nearly identical with the real one.A reference is used to write the algorithm.
Acknowledgements	This submission has inspired the following: NLMS Algorithm Demo, Recursive Least Square Identification without Noise
MATLAB release	MATLAB 6.0 (R12)
Other requirements	The sample data is created by the use of control system toolbox but it can easily created by any way else
Zip File Content
Other Files	Readme.txt, FIRsampledata, IIRsampledata, FIR_rls.m, IIR_rls.m

30 May 2002	Mark Jack	It is very interesting that RLS is one of the best adaptive algorithms. It converges very fast. In this code , the author used this method to provide a complete demo for the RLS with easy code.

06 Feb 2004	Fu-Sung Wang	The author does provide a good example for the beginners learning RLS algorithm. Furthermore, the stuff in the program is easy-understanding with lots of footnotes.
06 Feb 2004	Rob Kron	Perfect !
25 Mar 2004	Saeed Beyty	good, and helped in my home-works ! :D
07 Dec 2004	Ganapathy samy	excellant
08 Feb 2005	prabodh sahoo	Plz send me a rls algorithm demo for voice and speech signal.

08 Nov 2005	Raghuveer Allamneni	the demo gave the idea of RLS algorithm. can u please send me the RLS algorithm for channel equalization in mobile communication.
02 Dec 2005	Ahmad Firdaus Abdul Jalil	could u teach me how to model the transfer function(frequency domain) for a single output distillation process by using the ARX model
27 Dec 2005	Mangampu Silaban	Can you send me RLS program to recovery FECG from Abdominal ECG?

17 Oct 2006	Travis Wiens	Very nice rls example, but the IIR example is actually an FIR system and vice versa.

09 Dec 2007	Peyman Gholami	Hi
02 Feb 2008	a b	it is good.
07 Feb 2008	Peter van den Bosch	I think you switched IIR and FIR? IIR is the one that has both numerator and denominator (called FIR_rls.m in your scripts), isn't it? But thanks anyway ...

Updates
31 Oct 2003	Version 1.1 : 1- Two different demos one with FIR ( Feedback is used) and the other with IIR ( the input signal only is used) 2- No dependency on "Control System Toolbox" by adding sample data files
