qpsk ber curve
Hi all,
I have build a simulation system to test my Error Correcting Code.
And now I add modulation/demodulation module.
When I apply BPSK and QPSK to system, I found their BER versus SNR curve almost identical, is it right in theory?
My code rate is 0.9, code length >10000.
BTW, I found BPSK and QPSK have identical uncoded BER versus SNR curve, is above similar?
Any suggestions will be appreciated!
Best regards,
Davy
