مصطلحات موضوعية: Free Space Optics (FSO) technologies for satellite communications offer several advantages: wide bandwidth, high rate capability, immunity to electromagnetic interference and small equipment size. Thus, they are suitable for inter-satellite links, deep space communications and also for high data rate ground-to-satellite/satellite-to-ground communications. Nevertheless, FSO links suffer impairments that cause power signal degradation at the receiver. Scattering and absorption cause power signal attenuations predictable by suitable deterministic models. Optical turbulence causes random irradiance fluctuations which can generate signal fading events and can thereby only be predicted by statistical models. Attenuation and fading events can corrupt FSO links, and so it would be recommended to add mitigation error codes on the communication link. FSO channel can be described as an erasure channel: fading events can cause erasure errors. We have identified in rateless codes (RCs) a suitable solution to be employed in FSO links. RCs do not need feedback and they add a redundant coding on the source data that allows the receiver to recover the whole payload, despite erasure errors. We implemented two different of rateless codes: Luby Transform (LT) and Raptor. We analyzed their performances on a simulated turbulent GEO FSO downlink (1 Gbps - OOK modulation) at a 1,06 μm wavelength and for different values of zenith angles. Assuming a plane-wave propagation and employing Hufnagel-Valley, we modeled the downlink using: 1) a temporal correlated channel model based on Gamma-Gamma probability distribution and 2) an irradiance covariance function that we converted on a time function using Taylor frozen eddies hypothesis. Our new channel model is able to simulate irradiance fluctuations at different turbulence conditions as it will be shown in the full paper. We will also report performance results of LT and Raptor codes at overhead range varying between 0 and 50% and for different values of source packets, Settore ING-INF/01 - Elettronica, Settore ING-INF/03 - Telecomunicazioni
