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.

波束空间通信技术和架构，使千兆位移动的无线毫米波频率项目摘要智力优点：本项目的目标是开发新的无线通信架构的基本理论和设计策略，预计将提供变革性的增强，在访问和使用的电磁频谱毫米波频率。新的数据饥渴型移动的设备所带来的爆炸性带宽需求将很快超过当前网络所提供的兆比特/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：i）具有数量级更大带宽的毫米波系统，以及ii）可以利用空间维度在如此小的波长下实现变革性增益的多天线收发器。最先进的方法远远不能利用这些机会，因为它们未能解决毫米波频率固有的基本性能-复杂性权衡。正在寻求一种综合的理论-实验方法来开发新的收发器架构，该架构利用波束空间通信的概念将数据复用到不同的空间波束中，以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。调查是锚定在两个互补的架构，一个基于传统的阵列和数字波束形成和一个新的架构，使用一种新型的透镜阵列的模拟波束形成的组合提供了丰富的性能复杂性的途径。拟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。该项目的成果预计将使关键的业务能力，这是超越了国家的最先进的，包括电子多波束转向和跟踪在移动的点对多点的链接。更广泛的影响：该项目将提供一个宝贵的机会，多学科培训的学生在无线通信的前沿。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。研究结果将由PI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州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外联项目。从长远来看，该项目的成果预计将刺激在毫米波和更高频率的无线通信和传感新的跨学科研究。通过积极的工业合作和技术转让，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，以提供10-1000千兆比特/秒的速度。
