项目摘要

The Federal Communications Commission recognizes the need for the wireless industry to explore the 28-95 GHz millimeter-wave (mm-wave) bands where wider bandwidth is available, and future allocations may reach above 100 GHz. This explosion of mm-wave bandwidth opens up applications in 5G wireless systems spanning communications, localization, imaging, and radar. This project addresses fundamental scientific and engineering challenges in generating multiple parallel radio "beams" at mm-wave frequencies. A radio beam refers to a directional channel that establishes point-to-point contact for wireless communications and remote sensing. The ability to form a large number of such radio beams with high bandwidths will tremendously improve the performance for next-generation wireless systems. For example, multiple beams are essential for achieving the orders-of-magnitude increases in capacity, data rate, and geographical penetration required by the explosive growth in wireless applications. Moreover, they are important for both transmitters and receivers. The project will draw on an analogy between the spatial Fourier transform and a thin optical lens to obtain multiple wideband beams. Unlike lens-antenna-based approaches in the literature, this project will use a planar aperture antenna in conjunction with analog integrated circuits to generate many wideband mm-wave beams subject to power and size constraints. The proposed highly integrated approach is attractive for mobile applications including 5G smart devices, the internet of things, mobile robotics, and unmanned aerial vehicles, and other emerging applications focused on mm-waves. In addition to scientific research, the project will ensure that both minority students and female students will be mentored towards careers in mathematics, communications, as well as microwave circuits and systems. Educational materials will be developed for teaching array signal processing, microwave integrated circuit (IC) design, and ultra-high-speed analog signal processing. Principal Investigators (PIs) Madanayake and Mandal will organize a mini-conference to enhance microwave and mm-wave research activities at nearby universities in northeast Ohio. PI Madanayake will collaborate with co-PIs towards mentoring underrepresented students towards careers in Science, Technology, Engineering, and Math (STEM). The proposal team is uniquely placed to promote STEM topics spanning both electrical engineering and mathematics domains. The project will lead to education of the wider community on the importance of cross-disciplinary collaboration. Further, the team will strive to show the importance of learning deeper math topics towards success in technology and engineering careers.A multi-beam array receiver is deeply difficult to realize in IC form due to the underlying complexity of its signal flow graph. In this work, mathematical methods based on the theories of i) sparse factorization of structured complex matrices, and ii) approximate transforms are proposed to solve this problem. The resulting matrices are realized with multi-GHz bandwidths using analog ICs. One of the intellectual contributions is the development of efficient wideband beamformers based on sparse factorizations of delay Vandermonde matrices (DVM). This DVM algorithm solves the longstanding "beam squint" problem, i.e., the fact that the beam direction changes with input frequency, making true wideband operation impossible. Another is the derivation of transform matrices with specified properties that approximate the discrete Fourier transform (DFT). Such approximate transforms are not subjected to the known computational complexity bounds of the exact DFT, and approximate-DFT-based multi-beamformers can in fact be efficiently implemented using current-mode analog ICs. Finally, precision circuit design, digital calibration, built-in self-test, and other methods will be explored for efficiently realizing the proposed multi-beamforming networks in analog IC form.

联邦通信委员会认识到无线行业需要探索28-95 GHz毫米波（MM-WAVE）乐队，在该乐队中，可以使用更宽的带宽，未来的分配可能达到100 GHz以上。 MM波带宽的爆炸爆炸为5G无线系统的应用打开了跨越通信，本地化，成像和雷达的应用。该项目应对在MM波频率上产生多个平行的无线电“横梁”方面的基本科学和工程挑战。无线电梁是指建立无线通信和遥感的点对点触点的方向通道。形成大量具有高带宽的此类无线电梁的能力将极大地改善下一代无线系统的性能。例如，多个光束对于实现无线应用中爆炸性增长所需的容量，数据速率和地理渗透率的增加命令至关重要。此外，它们对于发射器和接收器都很重要。该项目将在空间傅立叶变换和薄光学镜头之间进行类比，以获得多个宽带梁。与文献中基于镜头的方法不同，该项目将使用平面孔径天线与模拟集成电路结合使用，以生成许多受功率和尺寸约束的宽带MM波梁。拟议的高度集成方法对于包括5G智能设备，物联网，移动机器人技术和无人机以及其他针对MM波的新兴应用程序在内的移动应用程序具有吸引力。除了科学研究外，该项目还将确保少数族裔学生和女学生都将受到数学，通讯以及微波电路和系统的职业的指导。将开发教育材料，用于教学阵列信号处理，微波集成电路（IC）设计和超高速度模拟信号处理。首席研究人员（PIS）Madanayake和Mandal将组织一个小型会议，以增强俄亥俄州东北大学附近大学的微波炉和MM波研究活动。 Pi Madanayake将与Co-Pis合作，以指导代表性不足的学生致力于科学，技术，工程和数学（STEM）的职业。该提案团队是独特的，以促进跨越电气工程和数学领域的STEM主题。该项目将导致更广泛的社区对跨学科合作的重要性进行教育。此外，团队将努力展示学习更深的数学主题对技术和工程职业成功的重要性。由于其信号流程图的潜在复杂性，因此很难以IC形式实现多光束阵列接收器。在这项工作中，基于i）结构化复合矩阵的稀疏分解的数学方法，ii）提出了近似变换来解决此问题。使用类似ICS使用多GHz带宽实现所得矩阵。智力贡献之一是基于延迟Vandermonde矩阵（DVM）的稀疏因素化的有效宽带束形式的发展。该DVM算法解决了长期存在的“光束斜视”问题，即光束方向随输入频率而变化，从而使真实的宽带操作变得不可能。另一个是具有近似离散傅立叶变换（DFT）的指定属性的变换矩阵的推导。这种近似变换不受精确DFT的已知计算复杂性界限，并且实际上可以使用电流模式模拟IC来有效地实现了基于DFT的多光向形式。最后，将探索精密电路设计，数字校准，内置的自我测试和其他方法，以有效地以模拟IC形式实现所提出的多标志性网络。
