Is there a relationship between Average energy of transmission and power saving
As mentioned in many books, the average energy of transmitted symbol is given by:
$E_s = (2/3)(M - 1) $
where $M$ indicated the modulation order.
Suppose that we are using in the first scenario $...

Determine minimum distance between two symbols in 16-QAM using the average symbol energy
If the probability of bit error for a square M-ary QAM is
$P_M = (1-(1-P_\sqrt{M})^2)$
where
$P_\sqrt{M} = 2(1-\frac{1}{\sqrt{M}})Q(\sqrt{\frac{3E_s}{(M-1)N_0}})$
and $E_s$ is the average symbol ...
