The Figure shows two constellation diagrams the first constellation diagram is of QPSK modulated system and second is of QAM signal with two Amplitude levels labelled A1 and A2. The two system have same probability of error. Then the correct statement regarding average transmitted power is
1
Average transmitted power in QPSK in more
2
Average transmitted power in QAM is more
3
Average transmitted power is same in both
4
Average transmitted power in QAM is more and is twice of QPSK
