FSO MIMO Communication Simulator

The FSO MIMO Communication Simulator is a comprehensive performance evaluation tool for Free-Space Optical (FSO) Multiple-Input Multiple-Output (MIMO) systems operating in atmosphe

Overview

The FSO MIMO Communication Simulator is a comprehensive performance evaluation tool for Free-Space Optical (FSO) Multiple-Input Multiple-Output (MIMO) systems operating in atmospheric environments. It enables researchers, engineers, and system designers to simulate the impact of atmospheric impairments and spatial diversity techniques on the performance of FSO MIMO systems. The simulator considers realistic channel effects such as atmospheric turbulence, scintillation, attenuation due to fog/haze/smoke, pointing errors, and angle-of-arrival (AOA) fluctuations. It supports different MIMO configurations (SISO, SIMO, MISO, MIMO) and spatial diversity combining techniques such as Equal Gain Combining (EGC), Maximal Ratio Combining (MRC), and Selection Combining (SelC).

Note: Distributed as a compiled .exe file with embedded MATLAB code. No source code will be provided. MATLAB Runtime (MCR) is sufficient.
