64-QAM BER in Time Varying Frequency Selective Channel

n_fft points is the FFT length and controls the frequency domain points (number of carriers)…n_tap is the number of channel taps in the time domain and controls the multipath interference…

Hi Dr. John,
Thank you for your effort helping us in the simulation of multipath fading channel.
Why did you get Hf from n-fft points instead of n-tap points?

Why did you use n_fft points in computing Hf instead of n_tap points?
