The integration of free-space optical (FSO) communications and relay technology has been envisioned as a promising and effective solution to achieve substantial performance gains for future deep space communications systems. In this article, the system performance of a dual-hop FSO/FSO relay framework for deep space communications is studied, to the best of our knowledge, for the first time, in the presence of plasma absorption, coronal turbulence, and pointing error impairments. More specifically, the Málaga fading distribution model is employed to characterize the coronal channel, since it has a large scope for the scintillation index ranging from weak to strong turbulence. In addition, we present closed-form expressions for the probability density function, the cumulative distribution function, the moment function, and the generalized moments function of the signal-to-noise ratio (SNR) for the whole system by …
