function r = rayleigh( fd, fs, Ns )

r = rayleigh(fd,fs,N)

A Rayleigh fading simulator based on Clarke s Model

Creates a Rayleigh random process with PSD determined

by the vehicle s speed.



INPUTS:

fd = doppler frequency

set fd = v*cos(theta)/lambda

v = velocity (meters per second)

lambda = carrier wavelength (meters)

theta = angle w/ respect to tangent (radians).

fs = sample frequency (Samples per second)

Ns = number of samples of the Rayleigh fading

process to produce



OUTPUTS:

r = row vector containing Ns samples of the Rayleigh

fading process
