This PFI: AIR Technology Translation project focuses on translating Full-Duplex (FD) technology to fill the need for efficient use of wireless spectrum resources in current and emerging wireless communication systems. FD technology is important because it allows wireless communication devices to receive and broadcast simultaneously, on the same frequency, thus effectively doubling spectrum utilization. The project will result in a prototype FD transceiver that can be easily integrated into current systems, leading to improved capacity and quality of service. By utilizing FD systems, spectrum assets worth billions of dollars can be redirected to create new opportunities for growth. This FD transceiver has the following unique features: a) Fully digital signal processing, b) reduced cost and c) compact footprint. These features allow for rapid deployment of compact, low cost, FD wireless systems capable of operating at double the spectral efficiency of competing Half-Duplex systems. By utilizing smart training heuristics that control a beam-steerable antenna and new digital cancellation transceiver architectures, a reduction of more than 100 dB of the self-interfering signal is achievable, thus allowing for FD communication. Technology gaps between research discovery and commercial application that will be addressed include developing new heuristics that are capable of adapting to the dynamic indoor and outdoor wireless channels, as well as novel robust channel estimation and non-linearity estimation and mitigation algorithms. Finally, new interference management and avoidance techniques will be designed to enable robust FD systems. The novelty of the proposed research is that it aims to bridge the gap between theoretical performance of FD systems and practical considerations that take into account the unique features associated with FD systems. In addition, undergraduate and graduate students affiliated with this project will receive structured innovation and entrepreneurship experiences through the University of California, Irvine, Institute for Innovation, which is a hub that connects a vibrant community of students, scholars, industries and entrepreneurs.

该PFI：AIR技术转换项目的重点是转换全双工（FD）技术，以满足当前和新兴无线通信系统中有效利用无线频谱资源的需求。FD技术很重要，因为它允许无线通信设备在相同频率上同时接收和广播，从而有效地使频谱利用率加倍。该项目将产生一个原型FD收发器，可以轻松集成到当前系统中，从而提高容量和服务质量。通过利用FD系统，价值数十亿美元的频谱资产可以重新定向，以创造新的增长机会。 该FD收发器具有以下独特功能：a）全数字信号处理，B）降低成本和c）紧凑的占地面积。这些功能允许快速部署紧凑、低成本的FD无线系统，其能够以竞争半双工系统的两倍频谱效率工作。通过利用控制波束可调天线的智能训练算法和新的数字消除收发器架构，可以实现自干扰信号的100 dB以上的降低，从而允许FD通信。研究发现和商业应用之间的技术差距将得到解决，包括开发能够适应动态室内和室外无线信道的新算法，以及新的鲁棒信道估计和非线性估计和缓解算法。最后，将设计新的干扰管理和避免技术，以实现强大的FD系统。所提出的研究的新奇在于，它的目的是弥合FD系统的理论性能和考虑到FD系统的独特功能的实际考虑之间的差距。此外，该项目的本科生和研究生将通过加州大学欧文分校创新研究所获得结构化的创新和创业经验，该研究所是一个连接学生，学者，行业和企业家的充满活力的社区的枢纽。
