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.

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.

well i want to record a speech signal with noise and want to apply it to the LMS algorithm to get out put so can anybody tell me whther i can do it in to matlab or not??
thank you

Thank you,it is really important and useful,but if there is a block diagram and flow chart,it will be more clear.

Thank you,it is really important and useful for my last project, but if there is a block diagram and flow chart,it will be more helpful to me. please send me the flowchart if you have it.
