Abstract
In this paper, we propose an SIM/SM system with a square-law combining. In an outdoor environment, the performance of SIM/SM deteriorates due to an atmospheric turbulence. The square-law combining technique can enhance the performance of the SIM/SM by employing square-and-integrate operation at the receiver side. For various spectral efficiencies, the performance gain increases as the number of photodetectors increases. Furthermore, as the turbulence strength increases, the performance gain also increases.
