Hi
Can anyone here give me more explanation abt independent complex zero mean Gaussian variables?

Regard,
 

Hi
It is looklike another IID random variables.
All samples and real part and imag part are independent.
If Z is complex zero mean guassian random variable with variance sigma2,
Z = sqrt(sigma2/2)*randn(1,1) + j*sqrt(sigma2/2)*randn(1,1)
 

I want to ask abt the meaning of that matter
Its regarded to noise
 

It just means the noise is complex. Both real and imaginary parts are zero mean Gaussian distributed. And they are mutually independent as well.
 

Hi ,

I kow what u mean for CZMCSG R.V.

Use this in matlab to generate this.

rand(0,1/sqrt(2),NR,NT).

But as u must need complec channel stuff for MIMO, so use this with it.

complex(rand(0,1/sqrt(2),NR,NT),rand(0,1/sqrt(2),NR,NT))

This will generate a complex ZMCSG (zero mean circulalry symmetric Gaussian) Random variable.

I guess will help you.

Press helped me !!!!
