In general, if I have a constellation of symbols, how can i calculate the energy por bit?
I think I should calculate the area of figure wich is formed linking external points in the space signal and divide it for the numer of bit compose the symbols.

Right?

Do you mean transmitted energy per bit? You would need the average transmit power and data rate for that, no?
