Wireless communications has had a major impact on a diverse range of areas such as economy, education, health, entertainment, logistics, and travel. In order to satisfy the ever-growing demand for higher data-rates and bandwidth, the fifth generation (5G) of wireless networks envisions communication in a spectrum which includes frequencies above 6 GHz and especially the millimeter wave (mm-wave) bands. The application of high carrier frequencies in mm-wave systems allows for larger channel bandwidths compared to the current RF (radio frequency) systems which operate in lower frequency bands. However, the energy consumption of constituent circuit and system components such as analog to digital converters (ADCs) and digital to analog converters (DACs) increases significantly with bandwidth. The massive number of transceiver antennas and large bandwidth lead to substantial ADC/DAC energy consumption in mm-wave multiple-input multiple-output (MIMO) systems which is inconsistent with the limited energy budget in mobile devices and small-cell access points. This points to an urgent need for energy-aware solutions to mm-wave transceiver design. The project addresses these challenges by proposing novel transceiver architectures, circuit blocks and design techniques, and associated communication strategies. The project will tightly integrate research with a significant education and outreach program consisting of two focus areas: (i) Student training, and (ii) Disseminating research outcomes in the forms of new curricular development and student involvement. A concerted effort will be made to broaden the participation of women and students from under-represented communities in the project.The project investigates the use of nonlinear analog operators and delay elements to mitigate the coarse quantization rate-loss in mm-wave communication systems, and develops an interdisciplinary framework for investigating the theory and practice of energy-efficient mm-wave communication through three interrelated thrusts. The first thrust develops the theoretical techniques necessary to study the fundamental limits of communication, such as achievable rates, in MIMO systems with low resolution ADC/DACs and nonlinear analog processing at the transceivers. The second thrust focuses on energy-efficient circuit design and on-chip implementation of nonlinear analog components and delay elements of Thrust 1. In particular, the Volterra-Weiner series representation of transistor nonlinearity is used to design nonlinear analog operators and analyze their performance. The third thrust reconciles the practical limitations of circuitry developed in Thrust 2, with the assumptions made in the theoretical derivations in Thrust 1, and proposes practical, implementable communication protocols for mm-wave communications. This includes the design of channel estimation, multiuser scheduling, and ADC allocation mechanisms for the proposed communication systems. The proposed research effort leads to a unified framework to study the circuit design and implementation of mm-wave transceivers, along with multiuser beamforming, scheduling, and data transmission mechanisms matched with the transceiver circuit design.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.

无线通信对经济，教育，健康，娱乐，物流和旅行等各种领域产生了重大影响。为了满足对更高数据速率和带宽的不断增长的需求，无线网络的第五代（5G）设想了一个频谱中的通信，其中包括6 GHz以上的频率，尤其是毫米波（MM-WAVE）。与当前在较低频带中运行的当前RF（射频）系统相比，高载波频率在MM波系统中的应用允许更大的通道带宽。但是，构成电路和系统组件的能源消耗，例如对数字转换器（ADC）和数字对模拟转换器（DAC）的类似物的能耗显着增加。 MM波多输入多输出（MIMO）系统的大量收发器天线和大带宽导致大量ADC/DAC能源消耗，这与移动设备和小型电池接入点的能源预算有限不一致。这表明迫切需要对MM波收发器设计的能源感知解决方案。该项目通过提出新颖的收发器架构，电路块和设计技术以及相关的通信策略来解决这些挑战。该项目将将研究与重大的教育和外展计划紧密整合，该计划包括两个重点领域：（i）学生培训和（ii）以新的课程发展和学生参与形式传播研究成果。将努力努力扩大该项目中代表性不足的社区的妇女和学生的参与。该项目调查了使用非线性模拟操作员的使用和延迟元素来减轻MM-Wave通信系统中的粗量化率损失，并开发了一个跨学科的框架，以调查能源和实践的能源效率高效的MM-Wave Mm-Wave通过三个相互互动的交流。第一个推力发展了研究通信的基本限制所必需的理论技术，例如可实现的速率，在低分辨率ADC/​​DACS和收发器的非线性模拟处理的MIMO系统中。第二个推力重点是节能电路设计和非线性模拟组件的片上实施以及推力1的延迟元素。特别是，晶体管非线性的Volterra-Weiner系列表示代表来设计非线性模拟操作员并分析其性能。第三个推力将推力2中开发的电路的实际局限性与推力1中的理论派生中的假设相结合，并提出了用于MM-WAVE通信的实用，可实施的通信协议。这包括针对拟议的通信系统的通道估计，多源调度和ADC分配机制的设计。拟议的研究工作导致了一个统一的框架，以研究MM-Wave收发器的电路设计和实施，以及与收发器电路设计相匹配的Multiuser beam成员，调度和数据传输机制。该奖项反映了NSF的法定任务，并被认为是通过基金会的知识优点和广泛的crietia crietia crietia crietia crietia crietia crietia crietia crietia crietia crietia crietia crietia crietia criteria criperia crietia crietia criperia recteria recteria rection thimia均值得通过评估。
