Alsalam alikom
well what all i need is some help from anyone who worked on DVB-T2 standard before.My problem is ,ok i used the LS method to get channel values at the pilots subcarrier then i must use interpolation to get the channel at other subcarriers, so i used linear interpolation for time domain and spline interpolation on freq domain, but when i want to compare between the actual channel and the estimated one, i find a great difference between them as shown in my first post!!!!
or it is better to plot the BER to if i am on the right way or not ??!!!!
so please can any one help me espically if he has an experience in DVB-T2 standard,OFDM part TX and RX
thanks so much in advance
by the way when i look in the standard in channel interpolation part, there is something called Nyquist rate or Nyquist limit , what does it mean ?? and if it is useful, how can i benefit from it in matlab m-file simulation
thanks again:razz::razz:
