Class JakesDistribution

java.lang.Object

ikr.simlib.distributions.Distribution

ikr.simlib.distributions.continuous.ContinuousDistribution

ikr.simlib.distributions.continuous.JakesDistribution

public class JakesDistribution
extends ContinuousDistribution

JakesDistribution implements a continuous distribution which delivers random variables in accordance with Jake's Doppler power density spectrum. Jake's power density spectrum is often used to model the distribution of Doppler shifts in a fading channel. The distribution delivers random variables according to Jake's spectrum between -Fdmax and +Fdmax.
