Abstract

In this paper, the performance of a multihop free-space optical system is studied. The system adopts all-optical amplify-and-forward relays and heterodyne differential phase-shift keying (DPSK) technique, considering Gamma-Gamma turbulence fading with pointing error. The novel closed-form expressions for the probability density function (PDF) and the cumulative distribution function (CDF) of the end-to-end signal-to-noise ratio (SNR) are derived. Based on these statistics, closed-form expressions for the outage probability, the average bit-error rate (BER), and the ergodic capacity of the all-optical relaying multihop system are presented. The analytical results are obtained.
