NeTS: Medium: Collaborative Research: In-Band Full-Duplex Underwater Acoustic Networks

海洋无线通信技术对科学、商业和国防行动至关重要，但仍然很原始，特别是在数据速率和可靠性方面。该项目开发了新的水声通信和网络策略，通过水下带内全双工（IBFD）水声网络来提高恶劣海洋环境下的网络效率。该项目通过让本科生和研究生接触跨学科研究，为他们创造了一个垂直整合的研究体验。通过与当地社区的合作，项目调查人员制定了外展计划，以吸引未来的学生，特别是那些来自少数民族和代表性不足的社区的学生，学习STEM学科。该项目的目标是开发创新的声学IBFD网络，其中包括：1)具有频谱效率的物理层接收器，能够消除声学特定的自干扰；2)通过IBFD提高网络效率的跨层协议。本项目以跨层、跨学科的研究方法为指导，包括四个研究任务：1)通过声学特定方法消除干扰；2)声学IBFD调制解调器和网络的原型设计；3)声学IBFD通信和网络的现场实验评估；4)跨层仿真和优化工具箱的开发。为了最大限度地提高成果，该项目利用了研究团队的一系列现有仪器、资源、工具和设计经验。

Wireless communication technologies in the ocean are critical to scientific, commercial, and national defense operations, and yet are still primitive, especially with respect to their data rates and reliability. This project develops new underwater acoustic communications and networking strategies to improve network efficiency in the harsh ocean environment, through underwater in-band full-duplex (IBFD) acoustic networks. The project creates a vertically integrated research experience for both undergraduate and graduate students by exposing them to interdisciplinary research. Through partnerships with local communities, the project investigators develop outreach programs to attract future students, especially those from minority and under-represented communities, to STEM disciplines.The objectives of the project is to develop innovative acoustic IBFD networks that contain: 1) spectrally efficient physical layer receivers capable of acoustic-specific self-interference cancellation, and 2) cross-layer protocols allowing enhanced network efficiency via IBFD. Guided by a cross-layer, interdisciplinary methodology, the project includes four research tasks: 1) Interference cancellation through acoustic-specific methods; 2) Prototyping of acoustic IBFD modems and networks, 3) Field experiments to evaluate acoustic IBFD communications and networking, and 4) Development of cross-layer simulation and optimization toolboxes. To maximize outcomes, this project leverages a range of existing instruments, resources, tools, and design experiences from the research team.
