The broader impact/commercial potential of this project is to enable the efficient use of wirelessspectrum. Over the last decade, the world has seen a sharp increase in the number and diversityof mobile devices. With this surge in mobile devices, access to spectrum has become anoverarching issue impacting the everyday life of citizens. The demand is expected to growexponentially in the coming years, with the rapid adoption of the Internet of Things (IoT) linkingeverything we interact with in daily life. The technology developed under this project will allowcommunication devices to listen and broadcast simultaneously, on the same frequency, thuseffectively doubling spectrum utilization by operating in Full Duplex (FD) mode. By improvingspectral efficiency and simplifying frequency planning, the results from this project will enablenewer paradigms for the rapid design, development and deployment of mobile devices. Societyas a whole will benefit from the increased array of applications enabled by robust, spectrallyefficient communication devices. Furthermore, valuable spectrum assets will be released and canbe redirected to create new opportunities for growth.This Small Business Innovation Research Phase I project will demonstrate a practical Full-duplexcommunication system prototype. The goal of the project is to develop a functional prototypeshowing the ability of fast cancellation that enables reliable full duplex operation at transmitpowers suitable for outdoor deployment. While Full Duplex has been shown to be achievableunder static channel conditions, maintaining the desired isolation between transmit and receivepath in a dynamic channel is difficult, mainly due to the high level of reflected power into theradio system that can limit its performance. By deploying novel and efficient cancellationmethodologies the prototype will be able to track and compensate for moving targets as theyappear in the radiation space of the FD system. Innovative co-designed spatial, analog and digitalapproaches will be used to converge on the optimal parameters for cancellation, while ensuringa rapid response time. All proposed algorithms under this project will be tested on a real-time FDprototype system, under realistic wireless channel condition, to ensure that practical issues areaccounted for.

该项目更广泛的影响/商业潜力是使无线频谱得到有效利用。在过去十年中，世界上移动的设备的数量和种类急剧增加。随着移动的设备的激增，频谱接入已成为影响公民日常生活的首要问题。随着物联网（IoT）的迅速采用，我们在日常生活中与之互动的一切都将被连接起来，预计未来几年的需求将呈指数级增长。该项目下开发的技术将允许通信设备在同一频率上同时收听和广播，从而有效地使全双工（FD）模式下的频谱利用率加倍。通过提高频谱效率和简化频率规划，该项目的成果将为移动的设备的快速设计、开发和部署提供新的范例。社会作为一个整体将受益于强大的，频谱效率高的通信设备所带来的应用程序的增加。此外，有价值的频谱资产将被释放，并可以重新定向，以创造新的增长机会。这个小企业创新研究第一阶段项目将展示一个实用的全方位通信系统原型。该项目的目标是开发一个功能原型，显示快速取消的能力，使可靠的全双工操作在适合户外部署的发射功率。虽然全双工在静态信道条件下是可行的，但在动态信道中保持发射和接收路径之间的理想隔离是困难的，主要是由于进入无线电系统的反射功率高，这会限制其性能。通过部署新颖有效的抵消方法，原型将能够跟踪和补偿移动目标，因为它们出现在FD系统的辐射空间.创新的协同设计的空间、模拟和数字方法将用于收敛到最佳的取消参数，同时确保快速的响应时间。本计画所提出之演算法将在一个即时的频分多址原型系统上，在真实的无线信道条件下进行测试，以确保实际的问题被考虑。
