WebThe channel impulse responses generated are formed of a single path with zero delay and a normally distributed fading coefficient. All time steps of a batch example share the same … Webassumed that the fading process is a Rayleigh fading process. The discrete samples of the Rayleigh fading process have a Rayleigh distribution and are correlated. For generating the Rayleigh fading coe–cients, three diﬁerent methods of random variate generations are used. The model proposed by Jakes [1] is a commonly accepted model of a ...
