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!
Hi,Could any one help me to provide me the code to generate OFDM With QPSK, And to reduce PAPR reduction analysis. please email me soon as possible. like to get in matlab(.m) file. email@example.com
