项目摘要

Wireless technology is heading for a spectrum crunch with the proliferation of data-hungry devices and applications. Millimeter-wave (mmW) technology, operating between 30GHz to 300GHz, is a promising emerging solution that offers orders-of-magnitude larger bandwidth than current systems and efficient spectrum usage through beamforming. While recent research shows the tremendous potential of mmW wireless in realizing unprecedented spectral efficiency, Gigabit rates and low latency, it is tempered by significant theoretical and technological challenges. In particular, the hardware complexity of the antennas and mmW circuits, and the computational complexity of digital processing challenge the current paradigms and require a fresh cross-disciplinary approach for addressing tradeoffs in performance, complexity, and energy consumption. This project is investigating fundamental tradeoffs in the design of wideband mmW wireless networks through an integrated framework spanning communication and signal processing techniques, hardware design, and networking protocols. The four-investigator research team is uniquely qualified to undertake this research due to their complementary expertise. The project is supporting six graduate students, and broadening participation in cutting-edge research to undergraduates and underrepresented groups through curriculum development and outreach efforts. Industrial relationships are informing research, providing opportunities for students, and facilitating technology transfer. A new cross-domain framework is being developed for integrated design of scalable mmW multiple-input, multiple-output (MIMO) networks that employ multi-antenna arrays for multi-beam multiuser communication. The research spans communication theory and signal processing, mmW hardware and data converter design, networking protocols, and experimental validation with a state-of-the-art testbed. The research is anchored on four goals: 1) Development of a multi-beam MIMO network architecture and communication/signal processing techniques for mobile access; 2) Investigation of a scalable and reconfigurable slice-based mmW transceiver design for multi-beam MIMO; 3) Investigation of medium access control and higher layer protocols to address mmW propagation challenges and to fully exploit the advanced physical layer capabilities; and 4) Integrated system modeling and assessment for performance-complexity-energy optimization and experimental validation. Several key operational requirements are being investigated, including multi-beam forming and data multiplexing, dynamic beam-frequency allocation and carrier aggregation, dynamic hardware reconfigurability, and flexible networking protocols for diverse use cases. The research results are expected to: i) advance the state-of-the-art of basic theory and design strategies for mmW wireless; ii) act as a catalyst for cross-disciplinary design and analysis of mmW wireless networks, and iii) lead to a deeper fundamental understanding and design methodologies which could impact other applications including imaging, sensing and radar.

无线技术正在沿频谱紧缩，随着数据渴望的设备和应用程序的扩散。在30GHz至300GHz之间运行的毫米波（MMW）技术是一种有前途的新兴解决方案，它的带宽比当前系统更大，并且通过横梁成式提供了有效的光谱使用情况。尽管最近的研究表明，MMW Wireless在实现前所未有的光谱效率，千兆速率和低潜伏期方面的巨大潜力，但它受到了重大理论和技术挑战的措施。特别是，天线和MMW电路的硬件复杂性以及数字处理的计算复杂性挑战了当前的范式，并需要采用新的跨学科方法来解决性能，复杂性和能源消耗方面的权衡。该项目正在通过跨越通信和信号处理技术，硬件设计和网络协议的集成框架来调查宽带MMW无线网络设计中的基本权衡。由于其互补的专业知识，这四个评论者研究团队具有独特的资格进行这项研究。该项目正在支持六名研究生，并通过课程发展和外展工作扩大了对本科生和代表性不足的团体的参与。工业关系为研究提供了信息，为学生提供了机会，并促进了技术转移。正在开发一个新的跨域框架，以集成可扩展的MMW多输入，多输出（MIMO）网络的集成设计，该网络采用多光束多源多源通信的多型安坦纳阵列。研究跨越通信理论和信号处理，MMW硬件和数据转换器设计，网络协议以及实验验证，并使用最先进的测试台进行了验证。该研究基于四个目标：1）开发用于移动访问的多光束MIMO网络架构和通信/信号处理技术； 2）研究用于多光束MIMO的可扩展和可重构切片的MMW收发器设计； 3）调查中等访问控制和更高的层协议，以应对MMW传播挑战并充分利用先进的物理层功能； 4）综合系统建模和评估性能 - 复杂性 - 能源优化和实验验证。正在研究几个关键的操作要求，包括多光束形成和数据多路复用，动态束频率分配和载波聚集，动态硬件可重构性以及用于不同用例的灵活网络协议。预计研究结果将是：i）推进MMW无线的基本理论和设计策略的最先进； ii）充当MMW无线网络的跨学科设计和分析的催化剂，iii）导致更深的基本理解和设计方法，可能会影响其他应用程序，包括成像，传感和雷达。
