Thanks.

I have a question about the "sampling frequency(Hz)" in the codes: how to choose the value? According to the carrier frequency or others?

BR,

thank you!!

helpful.
I think the code has little bug. It does not work if we set doppler shift (fd) is very small.
I made a small correction, and it works fine for me. just add one line.

fM=fd/fs; %normalized doppler shift
NfM=fftSize*fM;
kM=floor(NfM); %maximum freq of doppler filter in FFT samples

if (kM < 1) kM = 1; end % newly added line

% rest of the code
% ...

I am not sure though why it is like this, as I am not expert in channel analysis.
