项目摘要
Future wireless systems such as those proposed for the sixth generation of wireless networks (6G) will expand upon our present networking capability and provide for new and emerging services such as augmented/virtual reality, remote surgery, sensing, and imaging of our environment. This will require new wireless circuits and systems that are more precise than those required for previous generations of wireless networks. The goal of this research is to use machine learning to continuously improve the precision and accuracy of wireless circuits and systems. This can enable wireless devices to operate more efficiently and provide more robust wireless connectivity. The proposed investigation will also provide insight into embedding machine learning directly with RF transceiver hardware. This research that is focused on the investigation of CHIPS will result in the design of novel integrated circuit and integration techniques that are promising for 6G. In addition to the scientific outcomes of the investigation, this proposal involves international collaboration between universities in the United States and Taiwan. The educational objectives will cross-train 4 Ph. D. and 4 M.S. students between the partnering universities in both countries. The investigators also plan curriculum development for their undergraduate and graduate courses in circuits and systems design and plan to involve undergraduate students from their courses at earlier stages of their educational development in the research associated with the proposal.The objective of this proposal is to investigate the use of machine learning to continuously calibrate and optimize millimeter wave (mmWave) transceiver hardware. This is warranted because the projections for 6G expand the use of mmWave and near-THz spectrum, which require circuits and systems that can operate flexibly and with better linearity across wider instantaneous bandwidth. Commercially produced transceivers now use 100s-1000s of bits for trimming and calibration; however, many of these trims are only performed at the initial programming of the integrated circuit on automated testing equipment. This creates a large calibration and optimization space that this project will use to investigate continuous background optimizations using a local, efficient neuromorphic compute-in-memory system. As part of the program, highly trimmable digital transmitters will be integrated with a low-power calibration receiver that will be used to estimate transmitter parameters. The outputs of the receiver will be input into a neuromorphic computing accelerator with compute-in-memory (CIM) that will be running calibration/optimization algorithms that control the transmitters trimming and calibration bits. The project has two phases. In the first phase, the transceiver circuits and neuromorphic computing accelerator will be designed separately and characterized. They will be co-packaged for initial investigation of the interface between the systems. In the second phase, the experimental findings from phase one will be used to guide integration in phase two. The phase two demonstration experiment includes a fully integrated system and experiments on system optimizations to improve the system efficiency and linearity. The findings from these experiments will provide relevant information to scale designs for future systems that add complexity including multiple-input, multiple-output systems for wireless beamforming.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.
未来的无线系统,如那些为第六代无线网络(6G)提出的无线系统,将扩展我们目前的网络能力,并提供新的和新兴的服务,如增强/虚拟现实、远程手术、传感和环境成像。这将需要新的无线电路和系统,比前几代无线网络所需要的更精确。本研究的目标是利用机器学习不断提高无线电路和系统的精度和准确性。这可以使无线设备更有效地运行,并提供更强大的无线连接。拟议的调查还将提供直接将机器学习嵌入射频收发器硬件的见解。这项研究的重点是对芯片的调查,将导致新的集成电路和集成技术的设计,有望为6G。除了调查的科学成果外,这项提案还涉及美国和台湾大学之间的国际合作。教育目标是在两国合作大学之间交叉培养4名博士和4名硕士学生。研究人员还为电路和系统设计的本科和研究生课程制定了课程开发计划,并计划让处于教育发展早期阶段的本科学生参与与该提案相关的研究。本提案的目的是研究使用机器学习来持续校准和优化毫米波(mmWave)收发器硬件。这是有理由的,因为6G的预测扩展了毫米波和近太赫兹频谱的使用,这需要电路和系统能够灵活运行,并且在更宽的瞬时带宽上具有更好的线性度。商业生产的收发器现在使用100 -1000位进行修剪和校准;然而,许多这些调整只在自动测试设备上集成电路的初始编程时执行。这创造了一个大的校准和优化空间,该项目将使用一个局部的、高效的神经形态内存计算系统来研究持续的后台优化。作为该计划的一部分,高度可调的数字发射机将与一个低功率校准接收器集成,该接收器将用于估计发射机参数。接收器的输出将被输入到一个带有内存计算(CIM)的神经形态计算加速器中,该加速器将运行校准/优化算法,控制发射器的微调和校准位。该项目分为两个阶段。在第一阶段,收发电路和神经形态计算加速器将分别进行设计和表征。它们将被共同封装,用于对系统之间的接口进行初步调查。在第二阶段,第一阶段的实验结果将用于指导第二阶段的整合。第二阶段演示实验包括一个完全集成的系统和系统优化实验,以提高系统效率和线性度。这些实验的发现将为未来增加复杂性的系统(包括无线波束形成的多输入、多输出系统)的规模设计提供相关信息。该奖项反映了美国国家科学基金会的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
