  Is it possible to design spatial modulation based visible light communication system in optisystem 13?
  I have already analysed different modulation schemes in VLC system, now I want to analyse spatial modulaton? Please suggest.

  I am trying to design a sample but can’t. what I did is, I took a PRBS generator connected it to NRZ pulse generator and then gave input to Spatial LED. I didn’t use any connectors and directly used spatial PIN photodiode as receiver. Now, I used 3R generator and connected BER analyzer, Oscilloscope visualizer. Neither I get desired output pulse from Oscilloscope visualizer nor I got a clear eye pattern, min BER is 1 and Max Q factor and other analysed values are zero. Please help.

  Well, I replaced spatial PIN photodiode in the receiver with optical spatial receiver, I got good results. But, does using spatial LED instead of LED means it is spatial modulation. Please help with a sample design of spatial modulation for optical communication.
