Hi, Digicomm, thank you for the link, it's explained clearly there.

I just want to make sure 1 thing, from the example in the link that you gave, for 16-QAM, the average energy is 10 but the scaling factor is sqrt(10), is it because the RMS value is used instead of the abs value?

Will be waiting for the answer. Thank you

The first one is energy, the second one is amplitude.
