报告摘要：

水下无线通信在海洋监测、开发和巡航中扮演了重要的角色。本报告将阐述水下无线通信的挑战并介绍几种可行的中短距离水下无线通信系统解决方案，包括声学、磁感应及光通信方案。本报告将聚焦于中距离声学通信的最新进展，讲述对物理层技术（OFDM vs SCM及MIMO vs SISO）及网络层方法（轮询、CSMA、CDMA）的研究进展，并介绍基于声学和磁感应通信方法的应用实例及其在实际现场试验和海洋实验中的实验结果。

Underwater wireless communications plays an important role in ocean monitoring, exploitation, and surveillance. This talk will address the challenges of underwater wireless communications and introduce a couple of viable solutions to short- and medium-range underwater wireless communication systems, including acoustic, magneto-inductive, and optical communications. This talk will focus on recent progress in medium-range acoustic communications, providing tutorial understanding of physical-layer technologies (OFDM vs SCM and MIMO vs SISO) and network-layer approaches (Polling, CSMA, CDMA). Application examples based on the acoustic and MI communication means are also presented with results from practical field trials and ocean experiments.
