Multihop Relaying Over IM/DD FSO Systems With Pointing Errors
2015
Journal of Lightwave Technology
In this paper, the end-to-end performance of a multihop free-space optical system with amplify-and-forward channelstate-information-assisted or fixed-gain relays using intensity modulation with direct detection technique over Gamma-Gamma turbulence fading with pointing error impairments is studied. More specifically, novel closed-form results for the probability density function and the cumulative distribution function of the end-to-end signal-to-noise ratio (SNR) are derived in terms of the
