Abstract

In this paper, we consider a free-space optical communication system using subcarrier intensity modulation (SIM) with general-order rectangular quadrature amplitude modulation (QAM) and operating over Gamma–Gamma turbulence channels subjected to pointing errors. We derive novel, exact closed-form expression for the average symbol error probability of the considered system in terms of the Fox H function. Using the derived analytical results, we investigate the combined effects of turbulence-induced fading and misalignment-induced fading on the performance of the SIM-QAM FOS communication system. Numerical and computer simulation results are presented in order to verify the accuracy of the proposed mathematical analysis.
