在水中的无线传输主要是通过远程(但低速率)的水声通信或短距离(但高速率)的水下光通信来实现的。在本文中，我们感兴趣的是水下声学和光学之间是否存在统计关系。除了这种关系的理论意义之外，在同时具有声学和光学的多模式系统的背景下，通过声学预测光学链路的质量也是相关的。我们的研究基于北约ALOMEX 2015年探险期间获得的大量数据集。在这次实验中，我们同时测量了多个位置的声学和光学链路的几个特性，反映了海洋环境的多样性。我们的结果表明，声学链路的特性与光通信的可靠性之间具有很强的相关性。这种相关性使得能够在一定深度和范围内预测水下光链路的状态。由于声光通道的复杂性，我们无法找到这种关联的来源。因此，本文旨在促进对水声和光通信链路相互特性的理论研究。为了重现性，我们分享了实验处理后的数据。
Wireless transmissions in water are mostly carried out via long-range (but low-rate) underwater acoustic communications, or short-range (but high-rate) underwater optical communications. In this paper, we are interested in finding out whether a statistical relationship exists between underwater acoustics and optics. Besides the theoretical interest of such a relationship, predicting the quality of the optical link through acoustics is also relevant in the context of a multimodal system with both acoustics and optics. Our study is based on a large data set acquired during the NATO ALOMEX 2015 expedition. During this experiment, we simultaneously measured several characteristics of the acoustic and optical links at multiple locations, reflecting a diversity of sea environments. Our results show a strong correlation between the properties of the acoustic link and the reliability of optical communications. This correlation makes it possible to predict the state of the underwater optical link at a certain depth and range. Due to the complexity of the acoustic and optical channels, we could not find the source of this correlation. This paper is, therefore, aimed to stimulate a theoretical study of the mutual properties of underwater acoustic and optical communication links. For reproducibility, we share the processed data from the experiment.
