项目摘要

Wireless communication systems are increasingly covering every facet of our lives, including their use in mobile phones, healthcare delivery, autonomous driving, and space exploration. While wireless technologies are significantly changing the way our society is exploiting them for public safety and economic growth, they have resulted in an extremely congested radio spectrum. To address this challenge, innovative spectrum sharing solutions targeting new allocations at millimeter-wave frequencies (30-100 GHz), full-duplex spectrum usage and operation in under-utilized or unlicensed frequency bands are currently being considered. While the use of higher frequencies promises wider bandwidths and higher data-rates, these frequencies are not suitable for long-range communications and require expensive radio frequency (RF) hardware solutions. The main goal of this research is to address the nation's needs for spectrum sustainability, ubiquitous connectivity and increased national security for frequencies lower than 6 GHz, where the spectrum is more congested. In particular, this career development project will focus on RF co-designed fully-directional antenna interfaces that pave the way to efficient spectrum sharing through: i) full-duplex operation, ii) dynamic access of under-utilized and unlicensed frequency bands and iii) suppression of interference. The proposed research promises revolutionary improvements in spectrum sharing and allows for new capabilities in areas in which high-performance and high-density wireless technologies are of paramount importance, including next generation cellular communications, internet of things, and public safety. The program's broader educational goals include training of undergraduate and graduate students in areas related to next-generation RF systems, enhancing the Electrical Engineering (EE) curriculum at the University of Colorado Boulder with new class modules and a new class on tunable filter design techniques. The outreach activities will focus on broadening the participation of students in EE and promote higher education to traditionally under-represented populations including community-college students, veterans and women.The major objective of this proposal is to investigate and establish the theoretical foundations for highly-miniaturized and highly-reconfigurable RF front-ends through a new RF front-end design and integration concept based on RF co-designed fully-directional antenna interfaces that are in-field programmable and enable dynamic and efficient spectrum access. In particular, the proposed research will set the basic foundations for: i) fully-directional filter synthesis and design methods, ii) RF components with collocated signal processing capabilities and iii) multi-level transfer function tunability of the RF front-end chain. A specific focus of the research will be to understand the fundamental limits of spatio-temporal modulation and non-reciprocal filter design and determine trade-offs for various high-impact applications ranging for cellular to military and space communication systems. Tuning methods that facilitate multiple levels of transfer function reconfigurability will be developed, and their effectiveness in terms of efficient spectrum access will be studied. Furthermore, the trade-offs of size and performance of RF co-designed antenna interfaces will be systematically investigated. The proposed techniques will transform the way full-duplex radios are implemented and operated in spectrally-congested environments and will pave the way to generalized RF front-ends with multi-functional and multi-standard capabilities.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.

无线通信系统越来越多地涵盖了我们生活的各个方面，包括它们在手机中的使用，医疗保健提供，自动驾驶和太空探索。虽然无线技术正在显着改变我们社会为公共安全和经济增长而利用它们的方式，但它们导致了非常拥挤的无线电频谱。为了应对这一挑战，目前正在考虑目前正在考虑以毫米波频率（30-100 GHz），全双工频谱使用量和操作不足或未经许可的频带的运行的创新频谱共享解决方案。虽然较高频率的使用有望更宽的带宽和更高的数据率，但这些频率不适合长期通信，需要昂贵的射频（RF）硬件解决方案。这项研究的主要目的是满足国家对频谱可持续性，无处不在的连通性的需求，并提高了低于6 GHz的频率的国家安全，而频谱更加拥挤。特别是，该职业发展项目将集中于RF共同设计的完全方向天线界面，为有效的频谱共享铺平了道路：i）i）全双工操作，ii）动态访问未经限制和未经许可的频率带和III抑制的动态访问。拟议的研究有望在频谱共享方面进行革命性的改进，并允许在高性能和高密度无线技术至关重要的领域，包括下一代蜂窝通信，物联网和公共安全。该计划的更广泛的教育目标包括在与下一代RF系统有关的领域培训本科生和研究生，从而增强了科罗拉多大学博尔德大学的电气工程（EE）课程，并具有新的课程模块以及可调滤镜设计技术的新课程。宣传活动将着重于扩大学生参与EE，并将高等教育促进传统代表性不足的人群，包括社区大学的学生，退伍军人和妇女。该建议的主要目的是调查并建立高度调整和高度重新配置的RF RF前端的理论基础，以新的RF领域和整体设计为基础，并建立RF Front-Ender contern and rf-dern conteral rf-deastir，可编程并启用动态和高效频谱访问的接口。特别是，拟议的研究将为以下方面的基础设定：i）完全方向的滤波器合成和设计方法，ii）具有共处信号处理能力的RF组件以及III）RF前端链的多级传递功能可调性。该研究的一个具体重点是了解时空调制和非逆向滤波器设计的基本限制，并确定各种高度影响应用程序的权衡，这些应用程序与军事和太空通信系统有关。将开发促进多个传输函数可重构性的调谐方法，并将研究其在有效频谱访问方面的有效性。此外，将系统地研究RF共同设计的天线界面的大小和性能的权衡。所提出的技术将改变在频谱较高的环境中实施和操作的全维无线电的方式，并将为具有多功能和多功能功能的广义RF前端铺平道路。这奖反映了NSF的立法任务，并被认为是通过基金会的智力评论来评估的，并且值得通过评估来评估基金会的智力效果和宽广的范围。
