水声通信多径信道建模研究进展与展望

Research on modeling of underwater acoustic communication multipath channel

  • 摘要: 在海洋资源勘探、海洋安全维护、军事应用等领域,水下无线通信技术发挥着不可或缺的关键作用,其中水下声波通信是实现水下信息长距离稳定传输的主要手段。然而,当前水下声波通信仍面临诸多挑战,如何准确描述水声通信信道的实际状态,并进行恰当的建模,已成为当前学术界和工程界关注的焦点。因此,对水声通信多径信道建模方法进行分类和整理显得尤为重要。本文根据建模方法对信道的描述方式,将其分为确定性信道建模和随机性信道建模;按照建模原理进一步细化,确定性信道建模方法可分为基于物理分析的、基于测量的和基于数学理论的信道建模,随机性信道建模方法可分为几何随机信道建模和非几何随机信道建模。本文对现有信道建模方法进行时间脉络的总结、评述与对比,为深入研究和应用水声通信多径信道建模提供参考依据。

     

    Abstract: Underwater wireless communication technology plays an indispensable and crucial role in areas such as marine resource exploration, marine security maintenance, and military applications. Among them, underwater acoustic communication is the main means to achieve stable long-distance transmission of underwater information. However, current underwater acoustic communication still faces many challenges; accurately describing the actual state of underwater acoustic communication channels and conducting appropriate modeling has become a focus of attention in the current academic and engineering circles. Therefore, it is particularly important to classify and organize the multipath channel modeling methods for underwater acoustic communication. This paper categorizes these methods based on their approach to channel description into deterministic channel modeling and stochastic channel modeling. Further refining according to modeling principles, deterministic channel modeling methods are classified into physical analysis-based, measurement-based, and mathematical theory-based channel modeling, while stochastic channel modeling methods are divided into geometry-based stochastic modeling and non-geometry-based stochastic modeling. This paper provides a chronological summary, review, and comparison of the existing channel modeling methods, offering a reference for further research and application of underwater acoustic communication multipath channel modeling.
