Abstract

In this paper, we derive mathematical expressions for the evaluation of the average (ergodic) capacity of free-space optical (FSO) communication systems. Atmospheric turbulence conditions are modeled using the I-K distribution. Our newly derived expressions provide an efficient tool to assess the spectral efficiency of FSO communication systems. Numerically evaluated and computer simulation results are further provided to demonstrate the validity of the proposed mathematical analysis.
