      Hi Ranjeet,

      There is a basic problem with your design implementation that if you solve, you might get proper results for shorter transmission line. The settings of the OFDM modulator and OFDM demodulator are not the same. You should choose the same number of suncarriers and the same number of number of FFT points for them.

      Regards
