ParticipantHi!
I have been trying to use OptiSystem to simulate a coherent system using high-level modulation format such as 16-QAM with a DFE. However, I am not able to use the OptiSystem’s DFE module for this task and need to use Matlab to process data off-line. I wonder if there is a way to conduct this kind of simulation without using software other than OptiSystem.
Thanks

ParticipantHi,
Is there a specific reason why you can’t use OptiSystem’s electronic equalizer component?
Let me know if you have a project file that I can troubleshoot as well.
Regards

ParticipantThanks for the response. I can use the electronic equalizer for OOK system and was not able to use it in a coherent system setting. I would like to use the electronic equalizer for compensate chromatic dispersion but need to develop a Matlab program for this task. If there is some example file for this application, please let me know it.
Best Regards

ParticipantI’m looking into this for you. Is there a reason why you need to use an electronic equalizer? You could use our digital signal processing component to compensate for chromatic dispersion.

ParticipantThanks. I suppose that I can use the DSP component. It will be similar to the Matlab Co-Simulation method I plan to use. Just want to know if electronic equalizer can save us some time.
Best Regards,

ParticipantUnfortunately I haven’t figured out an easy way to incorporate our electronic equalizer with the 16 QAM signal. The EE was meant for binary type input signals.
You can disable/enable the types of compensation the DSP component will use though and insert your own Matlab code before or after it.
Let me know if you run into anymore problems!
