I have solved the problem.
“Convert Noise Bins” was not activated.
Thank you.
I saw that it is not about OFDM.
Then, what can be the problem?
Hi.
When we perform multi-itaration, we do not change any parameter. So, SNR, BER, and OSNR values are very close for each iterations.
In my opinion, this does not make any sense.
How can we plot BER/SNR graph?
Regards.
Thank you for your interest.
When I change the CW Laser power to 50 dBm, desirable results obtained. But, I do not know, 50 dBm power for laser is OK or not?
I really thank you for your help.
I attached the file. Channel and CW Laser are changed.
Thank you again.

Thank you for your answers.
Alitsu, that system is working well, but when i change the CW Laser parameters as Frequency=550 nm and Linewidth=300 GHz to cover whole visible range, results get worse. Do you have any idea aout this?
Thank you.
Hello Damian.
Your file 64QAM OFDM is OK, but when I change the parameters of CW Laser to the Visible Light conditions such as Frequency=550 nm and Linewidth=300 GHz, BER becomes unaccaptalbe. I choose those parameters to cover whole visible range like white light.
Thank you.
Best Regards.
I attached my system file.
Could you please help me regarding DSP block?
Thanks.

Dear Ravil and Sam Sung.
I attached my file. In this file, i tried to re-arrange an optisystem example from this website.
My problems:
1) I cannot LED as a light source. Also, I cannot use laser for visible range. Both of them gives no result or bad results.
2) In this file, if i use 4-QAM, there is no problem. But, if I use 16-QAM, i cannot get acceptable results.
Thank you.
Regards.
