This Small Business Innovation Research (SBIR) Phase II project aims to develop a real-time high-data-rate multicarrier underwater acoustic modem for aquatic applications. The modem to be developed will achieve a data rate that is more than one order of magnitude higher than all competing commercial products in challenging shallow water environments. It will have robust error performance in the presence of impulse-like noise and undesired disruptions. In addition, the modem will be power efficient to sustain long operation time, have a user-friendly interface, and maintain an easily-extendable architecture to facilitate advanced networking functionalities. Bringing the advanced multicarrier technology into the underwater modem market, this project solves one long-standing problem in the field, i.e., making multicarrier modulation work in underwater channels (earlier attempts all had only limited success). With one order of magnitude data rate increase, this project will significantly advance the state-of-the-art in underwater telemetry. The broader impact/commercial potential of this project is that the high-data-rate multicarrier underwater acoustic modem will significantly improve the operation of a wide range of aquatic applications, such as underwater environmental observation for scientific exploration, commercial exploitation, and coastline-protection/target-detection in military or anti-terrorism. It will also directly facilitate the development of emerging and fast-developing underwater wireless sensor networks and autonomous underwater vehicle networks. The significantly enhanced monitoring capability of aquatic environments will help us better understand and exploit the earth, preserve and protect it for our future generations. As more than 85% of underwater applications are envisioned to be in shallow water, this project will have enormous commercial impact in multiple market sectors including environment, energy, fishing, tourism, and national defense, etc.

该小型企业创新研究（SBIR）第二阶段项目旨在开发用于水生应用的实时高数据速率多载波水下声学调制解调器。待开发的调制解调器将在具有挑战性的浅水环境中实现比所有竞争商业产品高一个数量级以上的数据速率。它将在存在脉冲状噪声和不期望的中断的情况下具有鲁棒的误差性能。此外，该调制解调器将具有高能效，以维持长时间的操作，具有用户友好的界面，并保持易于扩展的架构，以促进先进的网络功能。本项目将先进的多载波技术引入水下调制解调器市场，解决了该领域长期存在的一个问题，即，使得多载波调制在水下信道中工作（早期的尝试都只有有限的成功）。随着一个数量级的数据速率的增加，该项目将显着推进水下遥测的最新技术。该项目更广泛的影响/商业潜力是，高数据速率多载波水声调制解调器将大大改善各种水生应用的运作，如用于科学勘探、商业开发的水下环境观测，以及军事或反恐中的海岸线保护/目标探测。它还将直接促进新兴和快速发展的水下无线传感器网络和自主水下航行器网络的发展。水环境监测能力的显著提高将有助于我们更好地了解和利用地球，为我们的后代保护和保护地球。由于超过85%的水下应用预计将在浅水中进行，因此该项目将在环境，能源，渔业，旅游和国防等多个市场领域产生巨大的商业影响。
