| 中文摘要: |
| 随着海洋探索和军事应用的迫切需求，水声通信需要向高数据率、高可靠性方向发展。正交频分复用技术被视为水声高速通信的新途径，并被成功应用于水声通信，在水声通信中展现了其优越性。高度灵活的自适应平台的发展，激发了可重编程水声调制解调器的发展，以适应不同实验/应用场景的需求。文中从带宽、调制方案、数据率、传输距离、误码率方面，介绍了国内外研究机构对可重编程正交频分复用水声调制解调器研究的进展，并对其中的技术进行概述。最后对可重编程正交频分复用水声调制解调器进行了展望。认为可重编程正交频分复用水声调制解调器需要的是分块接收处理的自适应实时扩展平台，同时也坚信水声网络的发展和需求必将推动智能水声通信的发展。 |
| 英文摘要: |
| With the urgent requirement of marine exploration and military application, underwater acoustic communication should be high-speed and reliable. Orthogonal frequency division multiplexing (OFDM) has been regarded as a new approach to underwater acoustic high-speed communication, and has been successfully applied to this field as well as shows its superiority. Besides, the highly flexible adaptive platform is progressing rapidly. It stimulates the development of reconfigurable and reprogrammable underwater acoustic modems which to adapt to the demand of different experiments/application scenarios. In this paper, the progress of the research on OFDM reconfigurable and reprogrammable underwater acoustic modems domestic and overseas is introduced from the aspects of bandwidth, modulation scheme, data rate, transmission distance and bit error rate. It also includes the overview of the technology. At the end of the paper, the future of OFDM reconfigurable and reprogrammable underwater acoustic modems is prospected. We deem it needs the platform with block receiving, adaptive, real-time and extensive, and believe the blossom of underwater network will promote the development of intelligent underwater acoustic communication. |
