Probability density function of turbulence fading in MRR free space optical link and its applications in MRR free space optical communications

Probability density function (PDF) of the modulating retro-reflector (MRR) turbulence fading channels is crucial for the performance analysis of MRR communication systems. In this study, closed-form expression for the PDF of normalised MRR free-space optical (FSO) turbulence fading coefficient is obtained first. Moreover, it is applied to the evaluations of the closed-form expressions for average capacity and outage probability of MRR FSO links. The effects of the parameters such as atmospheric turbulence conditions, communication distance, receiver aperture diameter and the average signal-to-noise ratio on the performance of MRR FSO links are discussed. Results show that in order to achieve successful MRR FSO communication, communication systems employing MRRs are suitable for short-distance communication in the case of low transmission power, besides quite high transmission power and large receiver aperture diameter are required simultaneously by long-distance MRR FSO communication.
