      In VLC, intensity modulation is used so that the modulated signal should be positive and real. But I see PSK is used as a modulation scheme for VLC in some papers. How can be PSK implemented in VLC? I am very confused about that.

      Dear Uykra,
      The PSK signal is represented by an amplitude and phase, which its field is defined as complex signal in OptiSystem. The amplitude is the square root of the intensity.
      Please refer to the examples on PSK in OptiSystem Example Library located at the following link for guidance.
