In this paper, we propose a Free-Space Optical (FSO) system model based on multiple subcarrier modulation (MSM) using M-ary Phase Shift Keying (M-ary PSK) scheme over Intensity Modulation Direct Detection optical link. We investigate the impact of aperture averaging on our model across weak-to-strong turbulence regimes taking into consideration the intermodulation distortion term due to the laser diode non-linearity. By using a modified model for aperture averaging technique, we also show that there is a design tradeoff between the receiver lens aperture and the required average Carrier-to-Noise and Distortion Ratio to achieve a given average bit error rate, ensuring substantial scintillation fade reduction.
