摘要
高数据率水声通信是海洋工程领域的一个重要研究方向,是实现水下信息传输的主要方式之一。首先,阐述了高数据率水声通信的两种主要类型:单载波时域均衡和正交频分复用;然后,给出了两种调制方式的发展现状及其优缺点;随后,介绍了该课题组近十年来在该领域的研究成果,特别是基于单载波频域均衡的高数据率水声通信;最后,对高数据率水声通信的进一步研究方向进行了展望。
High data-rate underwater acoustic（UWA） communication is an important research domain of oceanic engineering and underwater information transmission.First,the two main schemes of underwater acoustic communication are described,including single carrier with time-domain equalization（SC-TDE） and orthogonal frequency division multiplexing（OFDM）.Then,the development history and characteristics of those schemes are presented,and the research results of the research group in this area are given,in particular,the underwater acoustic communication based on single carrier with frequency domain equalization.Finally,the prospect of high-data rate underwater acoustic communications is protrayed.
