# Integration Matlab coding with Optisystem

Hi all,

I’m having a problem to integrate Matlab coding with Optisystem. Herewith I attach my basic design of optical access network. As u can see, at the receiver part I use Matlab component as demodulator after the PD (photodetector) component. Unfortunately, both PD and Matlab component doesn’t link to each other. Supposedly, the Matlab component will extract data output from PD component as an input to demodulate. But it takes modulation data directly as an input thus the results is not valid. May I know is there something to do with the PD component script? Or do I have to modify the Matlab coding so that it can read data from Optisys PD component? How is that possible?

Please help. Thanks in advance.
