I'm having trouble plotting rician pdf.
I have already managed to plot what i think is the empircal density funtction in a histogram.
What i need is a trace red line like this image:
so far i have this:
generated using this code:
u = 2;
s = sqrt(0.5);
% Generate in-phase component
X = normrnd( u, s, [1 randSamples]);
% Generate quadrature component
Y = normrnd( u, s, [1 randSamples]);
% Rician RV, S = sqrt( X^2 + Y^2 )
S = sqrt( X .^ 2 + Y .^ 2 );
% empirical probability density
[f,x] = ecdf(S);
ecdfhist(f,x, 20); hold on
How to get the red line?
This is the question for reference:
Hi Saad Khan,
You might want to smoothen the histogram.
Here is the example for understanding smoothening of histogram using "spline" command.
You might consider "ksdensity" for smoothening. Below code snippet is for better understanding.
s = [randn(100,1); randn(100,1)+k];
[f,x] = ksdensity(s);
These might help you.
