Hi
I would want to know if there a way to calculate SNR for a qpsk, 16 QAM and
64 QAM signals. I have been using the "divide" block, which has as inputs,
the signal that entries to the channel and a noise source fixed with the
voltage of noise that is fixed in the "channel model" block. Then, the
"divide" block's output goes to the "log10" block Would this be correct?
I copied this idea from another discussion.
