Abstract

In this article, we present an integrated terrestrial and satellite maritime communication system, where a shore-based terrestrial base station (TBS) and a low Earth orbit (LEO) satellite cooperatively provide wide-area communication services to maritime users. We conduct performance analysis for the integrated satellite-terrestrial maritime communication system. Specifically, we analyze the transmission rate and coverage probability of near-shore and off-shore users, respectively, according to the maritime communication environment. Besides, in order to better understand the impact of some key parameters, we also make asymptotic analysis in some special cases. Further, we design an optimization algorithm to maximize the coverage probability of near-shore users by adjusting the transmission power of TBS and the LEO satellite, while ensuring the both off-shore and near-shore users can meet the minimum communication rate requirements. Finally, extensive numerical analysis results verify the accuracy of the theoretical results and the effectiveness of the proposed optimization algorithm in the maritime communication system.

卫星-陆地一体化海上通信性能研究

在本文中，我们提出了一个陆地和卫星一体化的海上通信系统，其中岸基地面基站（TBS）和低地球轨道（LEO）卫星协同为海上用户提供广域通信服务。对卫星-陆地一体化海上通信系统进行了性能分析。具体来说，我们根据海上通信环境，分别分析了近岸和离岸用户的传输速率和覆盖概率。此外，为了更好地理解一些关键参数的影响，我们还对一些特殊情况进行了渐近分析。进一步设计优化算法，通过调整TBS和LEO卫星的发射功率，使近岸用户的覆盖概率最大化，同时保证近岸和离岸用户都能满足最小通信速率要求。最后，大量的数值分析结果验证了理论结果的准确性和所提优化算法在海上通信系统中的有效性。
