      Hi

      I want to connect OFDM Demodulation Dual-Polarization Block to
      QAM sequence decoder as shown in figure attached. From optisystem,
      I see that QAM sequence decoder is having two input ports but the
      figure shows it having four inport ports. How to make this as
      having four input ports ?

      regards
      Vamsy

      Dear Vamsi,
      Please note that the OFDM Demodulator has two components (I/Q) on each polarization (X/Y). Thus you need to have two QAM Sequence Decoders, one for each polarization.
      Please check the example (OFDM Coherent Detection Single Port Dual Polarization 16QAM.osd) at the following location for more information C:UsersUSER NAMEDocumentsOptiSystem 20.0 SamplesAdvanced modulation systemsOFDM systems.
