Hello,

I am doing a project related to the resource allocation in femocell. I am also facing this issue and your thread was very helpful for me, so thank you for that.

I wanted to ask you what exactly you did in your project ? so if any part is common I can reffer to your code of matlab.

If you are intersted in helping please let me know on mahimnat27@gmail.com

Kind Regards,

Mahimna

You need to generate points which have random angles smaller or equal to 2*pi and random radius smaller or equal to the circle radius, here is the code:

 n=100; % number of points that you want
 center = [1 ,2]; % center coordinates of the circle [x0,y0] 
 radius = 10; % radius of the circle
 angle = 2*pi*rand(n,1);
 r = radius*sqrt(rand(n,1));
 X = r.*cos(angle)+ center(1);
 Y = r.*sin(angle)+ center(2);
 plot(X,Y,'.k')
