ADD AWGN noise(channel ) to binary data and draw BER via SNR

[uni-pixel]

Hi everyone, 

I want to generate the 0 and 1...(it is very simple with for loop and random bit generator) , and add AWGN to it. HOw can I add AWGN to binary bits?

Also I want to plot BER TO SNR at the end of the plot. How can I do that in Labview?

Thank you so muc for your help
