Echo is a delayed and attenuated copy of the original. Because of reflections, you can get multiple copies (delayed and attenuated).
Therefore the echo model can be quite complex (same method is true for reverberation).
The difference between reverb and echo is the time delay hundreds of ms vs. sec.
so, it means that the signal must be inputed and just delayed it for it to become echo...But what if I already have the input signal that has an echo already what possible method to delete echo.What can you suggest for it to be removed.
HI
for producing echo u can use simulink and multiple delay blocks.
to delete echo, in theory aneefective way is the use of adaptive filters. adaptive filters have a wide usage in many communication and signal processing areas. if u are newbie in that; u may have a look in the books entitled: "adaptive filters".
e.g; the book :"adaptive filter theory" by S. Hayhin is awailable in EDA.
Cheers

There is a good final work which could help you. It is entitled "Implementing Reverberation Algorithms in Matlab" by Nicolas Holzem. See the attachment.
Hi
My purpose is that u can read books in the subject of "adaptive filters theory ". like the one that is written by S. Haykin. this book is already uploaded to the EDABOARD. if u search u can find it.
first you have to use data acuisition tool box to get signal with echo and you have to compare signal and the echo+signal and then you have to use adaptive filter and by using lms algortihm in matlab you can cancel echo perfectly.www.dsprelated.com may be helpful for you
hello, I have another problem the signal i used were recorded the far end and the near end then I put some delay for it to become echoic. these implementations are separated from each other. How can I integrate all of this?can anyone help me???:?:
