echo cancellation using matlab

Dear Sir/Madam
Please check the attachment to find matlab code for a simple Echo canceller. in this project (ECHO.M) we use a pure signal {sin(2khz)} as original speech signal and the echo signal in generated by using this original signal after adding a delayed version of it and also we have added a random noise to the echoed signal.
then by using LMS algorithm we have cleaned echofrom original signal. you can run it and see the learning curve of adaprive filter and .....,

with the best regards
Ramin
