Thank you very much, alistu and Mohamed. The BER analyzer worked and 16-QAM- OFDM system performance is increased.

Sorry about that, it’s here sir. In the attachments.

Thank you very much!

I tried your idea, but the BER Analyzer still doesn’t work. No results there.

My Bit rate was 10e+009, so I chose Symbol rate was 2.5e+009 ( in 16-QAM). What are my mistakes?

And one more question please, about Min BER. In my result at 4-QAM, the Min BER is the horizontal line, how can I adjust it ?

I look forward to hearing from you.

Thank you, alistu!

It’s my mistakes. I did it yesterday, like you say. But I still don’t know why we must change the frequency to 193.1075 of the Optical Filter and the PIN photodiode too.

More question, when i change the QAM modulation from 4 to 16 or 64 then the BER Analyzer isn’t work. What happened, so what should i do to correct?

Sorry to bother you, i’m not good student! Answer me if you have free time.

Best regards.
