HI GUYS,
could any of you send the code for echo cancellation using MATLAB ?i have a speech signal with interference..the interference is primarily because of the echo due to which the speech is not clear..so,give a code by virtue of which i could remove these echoes caused by reflection of sound waves from a wall of reflection coefficient of .5...the wall is 80 m apart..

regards
 

You can do it by yourself, by applying "adaptnlms" function and realising well-known structure from many of adaptive filtering books

For example Haykin "Adaptive filter theory"
