abstractecs - 0622125 r。该提案侧重于高数据速率超宽带（UWB）无线多输入多输出（MIMO）收发器的新理论和测试平台。提出的系统范例使用时间反转与非相干检测作为相干接收的替代方案。它利用敌对的、多路径的信道作为接收链的一部分。智力优势：本研究将首次从统一、连贯的角度研究时间反转UWBMIMO。统计通信理论、时域瞬变电磁学和现实原型的结合将使我们更好地理解自然的极限。如果提议的项目成功，将创建一个新的理论框架，并系统地应用于各种系统，包括无线、光学、声学和地震领域。这种新理论与相应的窄带MIMO理论有许多相似之处，但在其特有的瞬变电磁部分比窄带MIMO更加丰富，也更加困难，因为窄带MIMO与基于时间反转的UWB MIMO没有可比性。广泛的影响：提出的系统框架可以潜在地解决如何降低UWB社区收发器复杂性的最紧迫问题。这种低成本、低功耗、高数据速率的收发器将开辟无线网络和服务的新领域。这项提议的研究将有可能在许多领域带来革命性的突破。直接的应用包括科学和工程的各个方面，如无线工业、超宽带雷达和传感器、水下声学、遥感、图像引导治疗和手术。由于技术的进步，社会将在经济上受益。

AbstractECS-0622125R. Qiu, Tennessee Technological UniversityThis proposal focuses on a novel theory and testbed for high-data-rate ultrawideband (UWB) wireless multiple-input multiple-output (MIMO) transceivers. The proposed system paradigm uses time-reversal with noncoherent detection as an alternative to coherent reception. It exploits the hostile, rich-multipath channel as part of the receiver chain.Intellectual Merit: This research will be the first to investigate the time-reversal UWBMIMO from a unified, coherent view. The combination of statistical communication theory, time-domain transient electromagnetics and real-life prototyping will lead us to better understand the limits of nature. If the proposed project is successful, a new theoretical framework will be created and be systematically applied to various systems, including wireless, optical, acoustic, and seismic fields. This new theory has many resemblances to the corresponding narrowband MIMO theory, but in its peculiarly transient electromagnetic parts is incomparably richer, and more difficult than the narrowband MIMO that offers no analogies to the time-reversal based UWB MIMO.Broad Impacts: The proposed system framework can potentially be a solution to the most pressing problem of how to reduce transceiver complexity in UWB community. The lowcost, low-power, high-data-rate transceivers will open a new range of wireless networking and services. The proposed research will potentially lead to revolutionary breakthrough in many branches. The immediate applications include all aspects of science and engineering such as the wireless industry, UWB radar and sensors, underwater acoustics, remote sensing, and image-guided therapy and surgery. The society will be benefited economically due to the technological advancement.
