北卡罗莱纳州Lazzi，Gianluca目前大多数无线通信系统采用单极化或双极化天线元件阵列，每个天线元件能够测量电磁信号的至多两个分量。最近的研究结果表明，在一个丰富的散射环境中，无线链路的容量可以显着提高采用共定位，共极化天线，可以检测和激发电磁场的附加组件。 智力优势：该项目的目的是通过使用矢量传感器阵列来提高无线通信的性能，这些传感器阵列可以检测或激发底层电磁场的多达6个分量。该项目是射频天线设计和通信理论之间的跨学科努力。讨论了四个主要问题：（a）适用于无线通信的新型紧凑的平面矢量传感器天线，（B）用于精确预测这种天线的性能的新的计算工具，（c）矢量传感器通信系统的容量的信息理论研究，以便量化它们的优点并提取对阵列设计的见解，以及（d）新的调制，差错控制编码和利用这些天线提供的附加信息的接收机架构。这项工作的最终目标是更充分地挖掘无线电信道的潜力，并在此过程中降低无线通信的功率和带宽要求。 更广泛的影响：该项目是两名研究人员的共同努力，他们在天线和无线通信方面有着良好的记录，并有着成功的合作历史。这项研究将对我们的本科生和研究生产生直接影响，使他们接触到天线设计和无线通信的跨学科观点，将其视为一个不可分割的概念，而不是单独的工程学科。通过提供降低功率和带宽要求的新方法，以及通过在天线和通信系统设计中产生大量新概念，该活动还具有显著影响下一代商用无线系统的潜力。

ABSTRACT0312696Lazzi, GianlucaNorth Carolina StateMost wireless communication systems currently employ arrays of single- or dual-polarized antenna elements, each which is capable of measuring at most two components of the electromagnetic signal. Recent results in communication theory suggest that, in a rich scattering environment, the capacity of wireless links can be dramatically improved by employing co-located, co-polarized antennas that can detect and excite additional components of the electromagnetic field. Intellectual Merit: The aim of this project is to improve the performance of wireless communications through the use of arrays of vector sensors that can detect or excite up to 6 components of the underlying electromagnetic field. This project is an interdisciplinary effort between radio frequency antenna design and communication theory. Four main issues are addressed: (a) a new class of compact, planar vector-sensor antennas suitable for wireless communication, (b) new computational tools for accurately predicting the performance of such antennas, (c) an information-theoretic study of the capacity of vector-sensor communication systems, in order to quantify their advantages and extract insights into array design, and (d) new modulation, error-control coding, and receiver architectures that exploit the additional information provided by these antennas. The ultimate goal of this work is to more fully exploit the potential of wireless radio channels, and in the process reduce the power and bandwidth requirements of wireless communication. Broader Impact: This project is a joint effort between two investigators with established track records in antennas and wireless communication and a successful history of collaboration. This research will have a direct impact on our undergraduate and graduate students by exposing them to an interdisciplinary view of antenna design and wireless communications, seen as an indivisible concept rather than as separate engineering disciplines. This activity further has the potential to significantly impact the next generation of commercial wireless systems, by offering new approaches to reducing power and bandwidth requirements, and by generating a wealth of new concepts in antenna and communication system design.
