本文提出了一种地面与卫星一体化海上通信系统,其中岸基地面基站(TBS)和低地球轨道(LEO)卫星合作向海上用户提供广域通信服务。我们对该一体化卫星-地面海上通信系统进行性能分析。具体而言,根据海上通信环境分别分析近岸和离岸用户的传输速率和覆盖概率。此外,为更好理解一些关键参数的影响,还在一些特殊情况下进行渐近分析。进一步设计了一种优化算法,通过调整TBS和LEO卫星的发射功率来最大化近岸用户的覆盖概率,同时确保离岸和近岸用户都能满足最低通信速率要求。最后,大量数值分析结果验证了理论结果的准确性以及所提优化算法在海上通信系统中的有效性。
英文摘要
In this paper, we present an integrated terrestrial and satellite maritime communication system, where a shorebased 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.
