I am trying to calculate the SNR from the source to the destination of a Rayleigh flat-fading channel with AWGN using the following formula:

SNR = (P*(h_sd^2))/N0;

where P=transmit power

h_sd=channel gain

N0=noise variance

I know the transmit power is going to be a constant so I considered it to be 27dB.

I have modeled the channel gain as

h_sd=abs((sqrt(0.5))*(randn(1)+j*randn(1)));

Am I on the right track? and I have no idea how to get N0
