Optimization of an optical array receiver for deep-space optical communication during earth-mars conjunction phase

In this article, channel modeling, optimization of an optical receiver, and link analysis of a deep-space optical communication channel between a space-craft in MSO (Mars stationary orbit) and an optical receiver deployed on Earth are presented. The simulation results show that optimization of link parameters is essential to maximize the performance of an already power-starved deep-space communication link. The calculations of achievable data rates show that optical communication can provide an order of magnitude greater bandwidth compared to the current RF technology. This paper presents the analytical results during Earth-Mars conjunction phase, which represents the worst-case channel conditions for an optical communication channel between planet Earth and Mars.
