Path loss in multiuser mimo scenario

[naincy 0]

I want to plot a graph : ber vs SNR for multiuser mimo communication.Large scale fading contains path loss and shadowing.

Here I am defining my channel as G=H*D^1/2,

where H:channel coefficients for fast fading (raleigh)

           D:channel coefficients for slow fading(path loss and shadowing)

Is there any dependence of large scale fading on SNR.

Or  it will remain the same for all SNR values.
