Hello friends
I am working in project of mid-span optical phase conjugation, I got a clear constellation diagram but unfortunately with high BER (about 0.4). I think this is because the received signal wavelength is different from the transmitted signal wavelength due to the phase conjugation device. However, I want to calculate the system BER from the results obtained from constellation diagram block ( EVM ). note that I used the system of Dual polarization PDM 16QAM. therefore I have two values of EVM (for both polarization components) may any one help me please?
