Özet

Reconfigurable Intelligent Surfaces (RIS) is a prominent research topic in 6G to improve the user-perceived quality of experience when there is no line of sight between transmitter and receiver. Although it is highly popular for RF communication, the use of RIS for optical communication is in the preliminary stage. In this paper, the end-to-end channel of the RIS assisted FSO (Free Space Optics, FSO) communication system is analytically modeled using exponentiated Weibull distribution. The probability of the system outage is calculated under various turbulence conditions and receiver aperture diameters. The analytical and simulation results show that turbulence intensity and receiver aperture diameter significantly affect the system's outage probability. The probability of system outage increases with the turbulence intensity increase and the receiver aperture diameter decrease.
