hi everybody.
im doing a mini project of artificial noise.
my reference will be the paper from S.Goel and R.Negi which is 'Guaranteeing Secrecy using Artifcial Noise'
i manage to get some codes and modify it, however i didnt manage to get the correct result as been shown in the paper.

my concern is at the demodulation part of the codes.

i hope somebody can give ideas and any reference for this project.

i can put my codes if someone need to see it.
PM or email me so that we can share some ideas.

how do i measured a power of a random number.

if i generate a random number and then decompose into QR decomposition.
i take any column of Q from the QR decomposition as my artificial noise.
but how do i calculate its variance, its power and its distribution?
help me pls this is part of the codes.

Code: 
 A= randn(100)+j*randn(100);
        [q, r]=qr(A);
        u1=q(:,1); u2=q(:,2); u3=q(:,3); u4=q(:,4);

u1 will be column 1 and so on.

so i want to calculate the statistical value of u1.help.
