项目摘要

ECS-0636594Chik Yue, Carnegie Mellon UniversityECS-0636621Upamanyu Madhow, University of Santa BarbaraOur objective is to develop the system architecture, signal processing algorithms and integrated circuit techniques for a robust, quick set-up, point-to-point wireless link which achieves speeds of 10-40 Gbps over a range of several kilometers, using millimeter (mm) wave spectrum. Since these speeds are comparable to those of optical fiber, the outcome of this project enables a fail-safe hybrid communication backbone infrastructure, which can be deployed or restored rapidly in the events of disaster and emergency. The system employs a novel hierarchical architecture which meshes beamforming (to provide link margins sufficient to overcome the limitations of mm-wave propagation in harsh weather) and spatial multiplexing (to provide large spectral efficiency, of the order of tens of bits per second per Hertz, required to realize optical link speeds using channel bandwidths of only several GHz). Beamforming gains are obtained by electronically steerable monolithic arrays. Each such array is a subarray in a larger array, forming a spatially multiplexed virtual multiple-input, multiple-output (MIMO) system: the transmit subarrays send separate data streams, which are separated out at the receiver using spatial interference suppression techniques. Key elements of this mm-wave MIMO system are CMOS IC design for monolithic steerable sub-arrays, signal processing/hardware co-design to obtain algorithms implementable at such high speeds, and hybrid analog/digital processing to enable low-power operation. Substantial effort will go into establishing a cell-based, reusable design/modeling framework to enable CMOS mm-wave VLSI design. The new findings will be incorporated into undergraduate and graduate classes through small design projects. Intellectual Merit: This is an inherently interdisciplinary project whose success depends critically on intense interaction between the three PI's on this project, whose combined expertise spans CMOS IC design for communication applications (Yue), millimeter wave device and IC design (Rodwell) and signal processing for communication (Madhow). The proposed system is based on innovations at every level, including system concept, signal processing algorithms, and circuit design and packaging. Millimeter-wave MIMO provides spatial multiplexing in line of sight environments, and is therefore a completely new concept relative to MIMO at lower frequencies, which provides spatial multiplexing only in rich scattering environments. The electronically steerable sub-arrays are based on a unique row-column architecture amenable to monolithic realization. The innovation in the signal processing consists of drastic simplifications, including a hierarchical decomposition co-designed with the hardware. Circuit design at mm-wave frequencies push the limits of mixed signal design in low-cost CMOS processes, and our cell-based design framework has the potential of providing a systematic approach to such design. The baseband processing employs novel hybrid analog/digital processing techniques, in order to minimize the performance requirements on high-speed, high-cost, high-power analog-to-digital converters.Broader Impact: Millimeter-wave MIMO provides the first feasible approach to bridging the capacity gap between wireless and optical systems, which has applications ranging from homeland security (e.g., disaster recovery) to last mile connectivity for enterprise and residential settings. An additional breakthrough is in terms of the ease of deployment of LOS outdoor links, which becomes a simple operation of roughly pointing the transmitter and receiver at each other, rather than precisely aligning the transmit and receive antennas as done in current practice. In addition, the breakthroughs in mm-wave CMOS circuit design and packaging required by this demanding application have the potential for impact well beyond the specific system considered here, and will open up a host of opportunities for harnessing mm-wave spectrum at reasonable cost. The PIs all have strong records of technology transfer, and intend to leverage their strong contacts with the communications industry to push for technology transfer by widely disseminating the results of this work not only through publications, but also using hardware demonstrations easily accessible to visitors. The proposed research will have a significant impact on the undergraduate and graduate curriculum at the PIs' institutions in terms of driving innovations and updates in a number of courses in circuit design and communication systems. Well-established outreach mechanisms in the nanotech area will be used to involve women and minorities, including high school students, in this effort. Due to the inherently interdisciplinary nature of this project, the students involved will receive a broad education cutting across several areas of Electrical and Computer Engineering.
ECS-0636594Chik Yue,卡内基梅隆大学ECS-0636621Upamanyu Madow,圣巴巴拉大学我们的目标是开发系统架构、信号处理算法和集成电路技术,以实现稳健、快速设置、点对点的无线链路,使用毫米波频谱在几公里的范围内实现10-40 Gbps的速度。由于这些速度与光纤的速度相当,该项目的成果实现了故障安全的混合通信主干基础设施,可以在发生灾难和紧急情况时快速部署或恢复。该系统采用一种新颖的分层体系结构,其结合了波束形成(以提供足以克服恶劣天气中毫米波传播的限制的链路裕度)和空间多路复用(以提供高频谱效率,数量级为每赫兹几十比特/秒,需要使用仅几GHz的信道带宽来实现光学链路速度)。波束形成增益是通过电可控单片阵列获得的。每个这样的阵列都是较大阵列中的一个子阵列,形成一个空间多路复用的虚拟多输入多输出(MIMO)系统:发射子阵列发送单独的数据流,这些数据流在接收器使用空间干扰抑制技术分离出来。该毫米波MIMO系统的关键元素是用于单片可导向子阵列的CMOSIC设计、用于获得可在如此高的速度下实现的算法的信号处理/硬件协同设计以及用于实现低功率操作的混合模拟/数字处理。将在建立基于单元的、可重复使用的设计/建模框架方面进行大量工作,以实现CMOS毫米波VLSI设计。新的发现将通过小型设计项目纳入本科生和研究生的课堂。智力优势:这是一个本质上跨学科的项目,其成功关键取决于项目中三个PI之间的密切互动,他们的综合专业知识涵盖通信应用的CMOSIC设计(YUE)、毫米波器件和IC设计(Rodwell)以及通信的信号处理(MadHow)。该系统基于各个层面的创新,包括系统概念、信号处理算法以及电路设计和封装。毫米波MIMO在视线环境中提供空间多路复用,因此相对于仅在强散射环境中提供空间多路复用的MIMO而言,这是一个全新的概念。电可导向子阵列基于可单片实现的独特的行-列结构。信号处理方面的创新包括彻底的简化,包括与硬件共同设计的分层分解。毫米波频率下的电路设计突破了低成本CMOS工艺中混合信号设计的极限,我们的基于单元的设计框架有可能为这种设计提供一种系统的方法。基带处理采用新颖的混合模数处理技术,以最大限度地降低对高速、高成本、高功率模数转换器的性能要求。广泛影响:毫米波MIMO提供了第一个可行的方法来弥合无线和光学系统之间的容量差距,其应用范围从国土安全(例如灾难恢复)到企业和住宅环境的最后一英里连接。另一项突破是在LOS室外链路的易部性方面,这变成了一种简单的操作,即粗略地将发射器和接收器对准对方,而不是像当前实践中那样精确地对准发射和接收天线。此外,这一要求苛刻的应用所需的毫米波CMOS电路设计和封装方面的突破可能产生的影响远远超出这里所考虑的特定系统,并将为以合理的成本利用毫米波频谱提供大量机会。私人投资机构都有良好的技术转让记录,并打算利用其与通信业的密切联系,推动技术转让,不仅通过出版物广泛传播这项工作的成果,而且还利用参观者容易获得的硬件演示来推动技术转让。拟议的研究将在推动电路设计和通信系统的一些课程的创新和更新方面对私人投资机构的本科生和研究生课程产生重大影响。将利用纳米技术领域成熟的外联机制,让妇女和少数群体,包括高中生,参与这一努力。由于这个项目本质上是跨学科的,参与的学生将接受跨越电气和计算机工程几个领域的广泛教育。
