WebN discrete fading paths. Each path has its own delay and average power gain. A channel for which N = 1 is called a frequency-flat fading channel.A channel for which N > 1 is experienced as a frequency-selective fading channel by a signal of sufficiently wide bandwidth. A Rayleigh or Rician model for each path. Rayleigh fading is a statistical model for the effect of a propagation environment on a radio signal, such as that used by wireless devices.
