Can anyone tell how to add mutually uncorrelated local channel noise vector and global channel noise vector in MATLAB coding?
Noise vectors n ∼ N(0,Rn) and w ∼ N(0,Rw)

The Communication System Toolbox has the awgn function. Otherwise, I would use the randn function.
So for example you would define:
n = Rn*randn
w = Rw*randn
with the appropriate ‘size’ arguments to match your vectors.

My pleasure!
In my example, ‘Rn’ and ‘Rw’ are the standard deviations. If you define them instead to be variances, my example changes to:
n = sqrt(Rn)*randn
w = sqrt(Rw)*randn
in order to be consistent with the documentation for randn.

I cannot help you with that, unfortunately. Communications engineering is not an area of my expertise.
I suggest you post that as a new Question, as it is not directly related to this one.
