Outage Probability Analysis of Maritime FSO Links

Abstract

<p> In this paper, the outage probability of maritime free-space optical communication system is analyzed. Maritime turbulence channel is modeled by Lognormal distribution. Channel model includes the combined effect of turbulence, pointing error, angle-of-arrival (AOA) fluctuations, and attenuation. Pointing error and AOA fluctuations are assumed to be Beckmann and Rayleigh distributed, respectively. Turbulence power spectrum is considered to present the Kolmogorov characteristics and Rytov variance of a propagating Gaussian beam is obtained. The probability density function, cumulative distribution function and outage probability of maritime communication channel are obtained analytically. Outage performance of a maritime communication link is given depending on various parameters of the maritime environment, the Gaussian beam, and the communication system. </p>
