Zusammenfassung:	This paper analyzes the performance of the atmospheric optical subcarrier multiplexing (AO-SCM) systems and the atmospheric optical subcarrier-modulated code-division multiplexing (AO-CDM) systems. The average received carrier-to-interference-plus-noise ratio (CINR) of the AO-SCM systems and the AO-CDM systems on a turbulence channel with the scintillation and the nonlinearity of a laser diode is derived. It is shown that the received CINR of the AO-CDM systems is larger than that of the AO-SCM systems when the number of channels is four for the same optical modulation index (OMI), and vice versa, when the number of channels is 16 for the same OMI.
