Abstract

The Moon and its surrounding cislunar space have numerous unknowns, uncertainties, or partially charted phenomena that need to be investigated to determine the extent to which they affect cislunar communication. These include temperature fluctuations, spacecraft distance and velocity dynamics, surface roughness, and the diversity of propagation mechanisms. To develop robust and dynamically operative Cislunar space networks (CSNs), we need to analyze the communication system by incorporating inclusive models that account for the wide range of possible propagation environments and noise characteristics. In this paper, we consider that the communication signal can be subjected to both Gaussian and non-Gaussian noise, but also to different fading conditions. First, we analyze the communication link by showing the relationship between the brightness temperatures of the Moon and the equivalent noise temperature at the receiver of the Lunar Gateway. We propose to analyze the ergodic capacity and the outage probability, as they are essential metrics for the development of reliable communication. In particular, we model the noise with the additive symmetric alpha-stable distribution, which allows a generic analysis for Gaussian and non-Gaussian signal characteristics. Then, we present the closed-form bounds for the ergodic capacity and the outage probability. Finally, the results show the theoretically and operationally achievable performance bounds for the cislunar communication. To give insight into further designs, we also provide our results with comprehensive system settings that include mission objectives as well as orbital and system dynamics.
具有未知现象的星际通信性能和系统分析
月球及其周围的半月空间有许多未知数、不确定性或部分绘制的现象,需要对其进行调查,以确定它们对半月通信的影响程度。这些现象包括温度波动、航天器距离和速度动态、表面粗糙度以及传播机制的多样性。为了开发稳健且可动态运行的星月空间网络(CSN),我们需要分析通信系统,纳入考虑到各种可能传播环境和噪声特性的包容性模型。本文认为,通信信号既可能受到高斯噪声和非高斯噪声的影响,也可能受到不同衰减条件的影响。首先,我们通过展示月球亮度温度与月球网关接收器等效噪声温度之间的关系来分析通信链路。我们建议分析遍历容量和中断概率,因为它们是开发可靠通信的重要指标。特别是,我们用加性对称阿尔法稳定分布对噪声进行建模,这样就能对高斯和非高斯信号特征进行通用分析。然后,我们给出了遍历容量和中断概率的闭式边界。最后,结果显示了理论上和操作上可实现的星月通信性能边界。为了深入了解进一步的设计,我们还提供了包括任务目标以及轨道和系统动态在内的综合系统设置结果。
