Before that, you should add how much you are willing to pay for us to do your work. Surely it is worth something? If not, then why would we bother to do your job?

the world is very lucky that there are not too many people like you
sir kindly help me i want the code of LMS algorithm used in the adAPTIVE FILTER..kindly help me

Pls Yousef, am really interested in this smart antenna. What frequency was this antenna modeled for and is it suitable for broadband application?
