LMS Algorithm Demo

by

 

24 Jun 2003 (Updated )

A system identification by the usage of the LMS algorithm.

| Watch this File

File Information
Description

LMS (least mean-square) is one of adaptive filter algorithms. In this MATLAB file ,an experiment is made to identify a linear noisy system with the help of LMS algorithm. The weights of the estimated system is nearly identical with the real one.A reference is used to write the algorithm.

Acknowledgements

This file inspired Lms Algorithm Demonstration.

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.
