Hi Rajguru!
Thank you so much for your reply. But I resolved that issue. I tried to decrease the channel spacing from 100 GHz to 50 GHz, so it’s ok. Now I’m trying to use 16-QAM in my system.
And can I have another question? At the beginning, i worked in OFDM modulation sample, and I tryied to increase bit rate from 10 Ghz to 30 GHz, then I modified some parameters but the result is so bad. If you worked on same problem, could you give me some hints?

I’m very appreciated for your help? I’m still a newbie.
I attached my osd file below.
Best regards.
