      dear all,
      kindly i have question in design MIMO in FSO, I get value of q factor of 90. Are it is acceptable or not. And i have another question some research write (q factor and others write Q^2), and some research mention q factor unitless in other and in db
      i want to know the difference

      I think Q = sqrt (SNR). So Q^2 is a proportional to SNR and can be measured in dB. However, you can measure any value in dB, it is a log scale even if it is a unitless like SNR (Unitless).
      If you are using eye diagram, the Q factor is estimated from the Eye opening. So, it may take very large values in case the Eye is well opened.
