Hello,
I’m simulating a QPSK-RoFSO system, the problem is that when I use the BER analyzer in the system, it doesn’t give any results even though the system constellation gives a proper diagram, on the other hand when I replaced PRBS with the component BER test set, the value doesn’t seem to show minimum for a BER value as in a BER analyzer as we usually know for an acceptable value BER must be less than 10^-9 , it gives result of bit error rate quantitatively where only the decimal value appears with a higher value of 0.2 or 0.39, or the log BER value is displayed constantly – 1000.
So what is the maximum BER test set value for a good BER for the system?
And if I want to plot a BER graphically versus distance using a BER analyzer, what is the correct way to relate the BER test results with a BER analyzer to obtain a BER curve graphically?
.
