Hi,
If the Prob. of error for a modulation technique is
Pe1 = ½ erfc(Eb/No)
and another modulation technique has,
Pe2 = ½ erfc(2*Eb/No)
can I say that the modulation technique has 3dB power better performance than modulation technique 1?
My reason is that the second can give the same BER at half the Eb/No.
i.e. 20*log10(1/2) ≈ 3 dB
