I was trying to find channel frequency response of OFDM system by using pilot symbols and linear interpolation.I used matlab interp1() to interpolate. But the problem is I get NaN value for all subcarrier channels beyond the last pilot symbol. which is not correct.
What technic can I use to find estimation of those subcarriers that are out of range for interpolation?
Please suggest me some idea.
Thanks in advance!
I am doing my Thesis , and it is releated with OFDM system , I have seen your model and I am really interesed to understand it so please send me the description of this model. Or if it is upload where I can find it .
I am looking forward to hearing from you.
Thank you very much.
