how to simulate the log normal fading process over distance based on the autocorrelation model in matlab.generate white noise process and passes it through a first order filter with a pole at e-del/xc. assume xc=20m.d=0 to 200m .sampling the process over every mater.

Xc = 20;
ss = .01;
y = wgn(1,200*(1/ss));
for i = 1:length(y)
x(i) = y(i);
for j = 1:i
x(i) = x(i)+exp(-(i-j)/Xc)*y(j);
end
end
