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. WebRayleigh Scattering: Basic Mechanism One way to understand scattering is as follows: i) The incident E-field induces a time-varying dipole moment in the sphere (recall the electrostatics problem of a dielectric sphere in a uniform E-field from homework 3) ii) The time-varying dipole radiates like a Hertziandipole, and this radiation is the the pirates cuttin out
