    摘要:

    水声通信网络在海洋目标定位和导航、资源勘探和开发、环境感知和监测等领域有重要应用,其中水声信道特性研究及其建模与仿真是建立通信网络的基础,而目前水声通信网络中的信道建模与仿真尚未有公认的标准方法。因此,本文基于对水声信道传播特性的分析,探讨了典型水声信道特性给水声通信网络设计带来的挑战;对比了经验模型、声场模型、基于本征路径的多径信道模型和基于统计特性的时变信道模型等水声信道模型,仿真结果表明水声信道结构的变化明显影响接收性能;阐述了基于水声信道特性的水声网络仿真工具和方法,分析了其特点;最后进行了总结,并展望了未来水声通信网络信道建模与仿真的发展方向。

    Abstract:

    Underwater acoustic (UWA) communications and networks play important role in the field of marine object localization and navigation, resources exploration and mining, environment sensing and monitoring, et al. And UWA channel modeling and simulation is the basis for building UWA communication and networks. Therefore, in this paper, the characteristics of channel propagation have been investigated, and accordingly the challenges of designing the UWA networks have been discussed. Then some channel modeling methods have been compared, including empirical model, acoustic field model, multipath channel model with intrinsic path, time-varying channel model with statistics features, and the simulation results have shown that the channel variation will downgrade the performance of signal receiving. And then some networking simulation tools and methods based on underwater UWA characteristics have been discussed, and their advantages and disadvantages were explored. Finally, it summarizes and looks forward to the future development directions of UWA channel modeling and simulation for UWA communication and networks.
