EARS: Beamspace Communication Techniques and Architectures for Enabling Gigabit Mobile Wireless at Millimeter-Wave Frequencies

在毫米波频率下实现千兆移动无线的波束空间通信技术和体系结构项目摘要智力优势：该项目的目标是为新的无线通信体系结构开发基本理论和设计策略，这些体系结构有望在毫米波频率下的电磁频谱的访问和使用方面提供变革性的增强。新的数据饥渴移动设备带来的爆炸式带宽需求将很快超过当前网络提供的兆比特/秒速度。此外，在当前使用的频率上，根本没有足够的带宽可用。两种技术趋势提供了新的协同机会：1)带宽大几个数量级的毫米波系统，以及2)多天线收发器，可以利用空间维度在如此小的波长下实现变革性增益。由于无法解决毫米波频率固有的基本性能复杂性权衡，最先进的方法在利用这些机会方面明显不足。为了开发新的收发器架构，利用波束空间通信复用数据到不同空间波束的概念，充分利用空间自由度来提高功率效率、频谱效率、安全性和减少干扰，正在寻求一种集成的理论-实验方法。该研究基于两种互补的架构，一种是基于传统阵列和数字波束形成，另一种是使用新型透镜阵列进行模拟波束形成的新架构，其组合提供了一组丰富的性能复杂性路径。建议的研究活动包括优化天线阵列设计，传播信道建模，波束空间通信技术的发展，以及基于原型的评估。该项目的成果有望实现最先进技术无法企及的关键作战能力，包括移动点对多点链路中的电子多波束转向和跟踪。更广泛的影响：该项目将为无线通信前沿的学生提供宝贵的多学科培训机会。研究成果将通过会议和期刊出版物、研究研讨会和互联网广泛传播。研究成果将通过讲座和课程项目纳入现有课程。代表性不足的本科生和研究生将通过威斯康星大学现有的成功项目参与该项目。初中和高中教师将参与科学和工程拓展项目。从长远来看，这个项目的成果有望在毫米波和更高频率的无线通信和传感领域激发新的跨学科研究。通过积极的产业合作和技术转让，该项目的成果预计将影响新兴毫米波宽带无线技术的概念、开发、标准化和商业化，以实现10-1000千兆位/秒的速度。

Beamspace Communication Techniques and Architectures for EnablingGigabit Mobile Wireless at Millimeter-Wave FrequenciesProject AbstractIntellectual Merit: The objective of this project is to develop basic theory and design strategies for new wireless communication architectures that are expected to deliver transformative enhancements in the access to, and usage of, the electromagnetic spectrum at millimeter-wave frequencies. The exploding bandwidth requirements imposed by the new data-hungry mobile devices will soon outgrow the Megabits/sec speeds offered by current networks. Additionally, there is simply not enough bandwidth available at the currently used frequencies. Two technological trends offer new synergistic opportunities: i) millimeter-wave systems with orders-of-magnitude larger bandwidths, and ii) multi-antenna transceivers that can exploit the spatial dimension for transformative gains at such small wavelengths. State-of-the-art approaches fall significantly short of harnessing the opportunities because of their failure to address fundamental performance-complexity tradeoffs inherent at millimeter-wave frequencies. An integrated theoretical-experimental approach is being pursued for developing new transceiver architectures that leverage the concept of beamspace communication multiplexing data into distinct spatial beams to fully harness the spatial degrees of freedom for enhanced power efficiency, spectral efficiency, security, and reduced interference. The investigation is anchored on two complementary architectures one based on conventional arrays and digital beamforming and a new architecture that uses a novel lens array for analog beamforming whose combinations offer a rich set of performance-complexity pathways. The proposed research activities include optimized antenna array design, propagation channel modeling, development of beamspace communication techniques, and prototype-based evaluation. The results of the project are expected to enable critical operational capabilities that are beyond the reach of the state-of-the-art, including electronic multi-beam steering and tracking in mobile point-to-multipoint links.Broader Impacts: The project will provide an invaluable opportunity for multi-disciplinary training of students at the cutting-edge of wireless communications. Research results will be broadly disseminated through conference and journal publications, research seminars, and via the internet. Research findings will be incorporated by the PIs into existing courses through lectures and course projects. Under-represented undergraduate and graduate students will be involved in the project through existing successful programs at the University of Wisconsin. Middle- and high-school teachers will be engaged in the project for outreach in science and engineering. In the longer term, the results of this project are expected to spur new interdisciplinary research in wireless communication and sensing at millimeter-wave and higher frequencies. Through proactive industrial collaborations and technology transfer, the results of the project are expected to impact the conception, development, standardization and commercialization of emerging millimeter-wave broadband wireless technologies for delivering 10-1000 Gigabits/s speeds.
