Homework Statement
I have an autocorrelation function given by
R([itex]\tau[/itex]) = [itex]J_0[/itex](2[itex]\pi[/itex][itex]f_d[/itex][itex]\tau[/itex])
I have already plotted it in Matlab using the following commands
ts=0.0000001;
fs=1/ts;
fd=100;
tau=0:0.0000001:0.05;
R=besselj(0,2*pi*fd.*tau);
How do I plot its PSD in Matlab and the plotted picture looks like this:

Homework Equations
The Attempt at a Solution
When I use the command pwelch(R), it just won't yield the picture.

I will obtain something different. How do I scale it so that I will resemble the picture given. thanks
