Hi Damian,
Thank you for responding to my issue. I believe the issue begins at the power combining stage before the transmission via the optical fiber. Or it could be an issue faced because of the code. I generated the code manually using Matlab, and have based the encoding and decoding sections based on this code. The codes are mentioned on the respective encoders. I hope the issue is a rather simple one i seem to be overlooking. I have attached the initial osd project.
Regards
