Time Varying Channel

[David]

Hi, everyone

I am having difficulties in generating a time varying Rayleigh fading channel.
Specifically, I do not know how to generate channel tap coefficients whose
autocorrelation function is defined by the Jake model.

What I have done so far is the following,

X=randn(1, 10000);
Y=randn(1, 10000);
Z=X+j.*Y;

Auto_Z = xcorr(Z);
plot(Auto_Z);

The plot does not follow the Jake model which is a Bessel function. Perhaps,
you can tell me what I did was wrong. Or any suggestion is greatly
appreciated.

Thank you.

David
