The broader impact/commercial potential of this PFI project is enabling reliable wireless communications in several underwater technology markets which include ocean exploration and discovery, underwater recreation, fishery industry, subsea oil and gas industry, underwater environmental and infrastructure monitoring, and military. The project aims at increasing reliability and information data rates in underwater wireless communication links by an order of magnitude over existing technologies. When applied to Autonomous Underwater Vehicles (AUVs) and wireless sensor networks, the proposed technology leads to great potential in reducing operational costs, improving efficiency, reducing safety risks, and enabling new capabilities such as Internet of Underwater Things (IoUT). The development of multidisciplinary education and student training from both engineering and entrepreneurial perspectives further impacts the next generation workforce by attracting women and underrepresented groups.The proposed project bridges the knowledge gap between Matlab post-processing and real-time hardware implementations of Multiple-Input Multiple-Output (MIMO) Turbo transceivers. A MIMO transceiver transmits multiple data streams via multiple transmit elements to increase data rate, and uses multiple receive elements to improve the reliability. The past research of the principle investigator have demonstrates via ocean experiments and post processing that Turbo receiver is effective in combatting hostile underwater acoustic communication channels by utilizing advanced error-correction coding and channel equalization. The main goal of this project is to design and validate a prototype that demonstrates real-time operation of the MIMO Turbo transceiver in underwater acoustic environment, achieving 50 - 100 kilo-bits-per-second (kbps) information data rate over 1 - 10 km distance and at 99.99% reliability. This is at least an order of magnitude improvement over existing underwater acoustic communication systems.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该PFI项目的更广泛的影响/商业潜力是在几个水下技术市场中实现可靠的无线通信，包括海洋勘探和发现，水下娱乐，渔业行业，海底石油和天然气行业，水下环境和基础设施监测以及军事。该项目的目的是通过与现有技术相比，通过水下无线通信链接中的可靠性和信息数据速率提高。当应用于自动水下车辆（AUV）和无线传感器网络时，提议的技术会带来巨大的潜力，可以降低运营成本，提高效率，降低安全风险，并启用诸如Internoft of Insterwater事物（IOUT）等新功能（IOUT）。通过吸引妇女和代表性不足的群体，从工程和企业家角度开始的多学科教育和学生培训的发展进一步影响了下一代劳动力。拟议的项目弥合了MATLAB后后处理与实时硬件实施的知识差距（MIMO多输出（MIMO）TURBO TURBO PERACEVER之间的知识差距。 MIMO收发器通过多个传输元素传输多个数据流以提高数据速率，并使用多个接收元素来提高可靠性。原则研究者的过去研究通过海洋实验和加工后证明，涡轮接收器可以通过利用高级错误校正编码和通道均衡来对抗敌对的水下声学通信通道。该项目的主要目的是设计和验证一个原型，该原型在水下声学环境中展示了MIMO Turbo收发器的实时操作，以超过1-10 km的距离和99.99％的可靠性，达到50-100千 - 比特（KBPS）信息数据速率。这至少是对现有水下声学通信系统的数量级改进。该奖项反映了NSF的法定任务，并且使用基金会的知识分子优点和更广泛的影响标准，被认为值得通过评估来获得支持。
