Yes, I understand that d_m is like time here, and it would be perfectly fine if fD would stay constant during the whole simulation. But as fD changes over time, the phase change from one sample to another (due to the same change in dopplers shift) will be amplified over time. AFAIS, this changes the autocorrelation properties over time. I would have expected something like tap[n+1] = tap[n] exp(2*pi*i*fD*cos(alpha)) Best, Bastian
