      Hi all,

      I am developing a system that cosimulates the Radio-over-Fiber transmission of CP-OFDM signals with MATLAB. I generate the signal in MATLAB and apply the carrier (3.5GHz) and then enter Optisystem. In Optisystem I only have a CW laser and a MZM to modulate the RF signal, a fiber, and a photodiode (see image attached). Then I go back with the resulting signal to MATLAB and evaluate the EVM.

      The problem is, while I have very good values of OFDM, they don’t vary with the fiber length as expected.

      Has anyone tried a similar setup, or could anyone give some insight into this? It’d be much appreciated.

      Thank you

      Hello Alvaro,
      We can check your project if you would send the OptiSystem project and the Matlab codes as a zip file to ahmad.atieh@optiwave.com.

      Hello Ahmad,

      thank you for your offering, we were already able to solve the problem. In fact it was my fail.
