Thread: Echo cancellation matlab code

hello there...
I am really desperate, frustrated and totally freaked out on my project...
How will I going to integrate the functions given in matlab like the NLMS non-linear processor, the adaptive filter the double-talk detector into one matlab code and be able to come up with my sole objective which is TO CANCELL ECHO.Please help me and share your brilliant ideas...I know you have gone the best education.

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

Salam agha Ramin

Could you please explain how i can create a spread sheet in Excell functioning the same as the attached file?

Thank you

Thanks for the code.

Good morning Mr Ramin. I am having problems trying to filter a sine signal with added random noise using the LMS algorithm. Would you be so kind as to help me by sending a matlab code with something similar? My email address is :
