Hi
I am trying to re-simulate an inter-satellite optical wireless communication system (IsOWC) system using the QPSK modulation system on OptiSystem 12. I’m referencing a particular paper and I can’t seem to achieve the same results. The referenced design achieved a Q-factor of 2248.59 and a BER of 0 for a 400Gbps system operating at a range of 4767km. When re-simulated for the same parameters, I achieved a Q-factor of 7 and a BER of 10^-12. I’m not entirely sure if I’m using certain components correctly.
The link to the referenced paper is attached below:

Would very much appreciate a second opinion.
Thank you.
