I have solved the problem.

“Convert Noise Bins” was not activated.

Thank you.

[Metin OzturkParticipant]

I saw that it is not about OFDM.

Then, what can be the problem?

[Metin OzturkParticipant]

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.

[Metin OzturkParticipant]

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?

[Metin OzturkParticipant]

I really thank you for your help.

I attached the file. Channel and CW Laser are changed.

Thank you again.

[Metin OzturkParticipant]

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.

[Metin OzturkParticipant]

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.

[Metin OzturkParticipant]

Hi Sam.

Thank you for your answer.

Could you please help me inserting DSP to my system?

How can I do this?

Thanks.

Also, my screenshots are in the attachment.

Thank you for your valuable help.

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.

Thank you Bryan.

I have just send an e-mail.
