DD-optical OFDM

[Kam]

Hi.
I am studying and simulating dd-optical ofdm. and i am remaking and trying to simulate the builtin dd ofdm circuit . In this circuit loop control is used for increasing the fiber length, and i just dont want to use it so i am just directly connecting the 50km OF to the photodetector, but by doing that the ber becomes 1 and constellation diagram also gets different location point or phase is changed. Can anyone please tell me why is this happening.?
Thank you.

Hi Kam,

Would you be able to upload your file in a ZIP folder so i can have a look at it and try to answer your question.

Thanks,

Josh

Thanks alot for replying Joshua. Please find the zip folder attached. there are two files in it. one is the original/reference file i took from optiwave examples named “direct detection optical ofdm system” and the other file which i have made which is exactly the same as the reference file is “practice dd-oofdm”. Thank you .
