Dear Damian,
I cannot upload the files here, but I will send them to your mail. I have implemented my own OFDM modulation and demodulation blocks and writing an OFDM program is not that complicated, so I don’t think the problem stems from my Matlab OFDM program. Besides, as I demonstrated to you before in my project files and screenshots attached via mail, the same OFDM program results in different constellation diagrams in Optisystem 12 and Optisystem 13. In fact, I’m still waiting for your reply to that mail, verifying that the problem was actually because of some bug in Optisystem 12. Here I have attached that constellation diagram what happened to it in Optisystem 12 using the same program as I have used here.
Thank you and appreciate Optiwave Team’s help and support.
