"WebSo the Doppler effects determine the rate at which the amplitude of the resulting composite signal changes. Doppler Power Spectrum The models behind Rayleigh or Rician fading assume that many waves arrive each with its own random angle of arrival (thus with its own Doppler shift), which is uniformly distributed within [0, 2 p ], independently of other waves.
