FSO System based on QPSK mod.

Hello everyone!

I have some problems with modeling FSO system (see attached file) – cant get correct constellation, eye diagramm and BER. As example take “Coherent derection QPSK system” and replace loop by “FSO Channel”, then try to change any parameter.
Have some versions about solving, but cant deal with it:
1 – choose wrong amplitudes for m-ary threshold detectors
2 – speed parameters (like bitrate and symbol rate) not сonformed on Tx – Rx

Will be glad for any advice or comment. Thanks!

      Hello Roman,
      please send me your project as a zip file to ahmad.atieh@optiwave.com to check it?
