I’m making the OFDM WDM project. And when i’m trying to figure BER vs SNR, I realize we can’t get BER = 10e-012 because the limit of sequence lenght is 2^30 bits. But in some paper use Optisystem for simulation , I see they can get BER with wide change (example: 10^-2 to 10^-12). So how can I do that?
If you have time please answer me.
