EARS: Collaborative Research: Full Duplex for Cognitive Networks

随着数据通信的新频谱变得可用，开发认知网络技术变得越来越重要，这种技术可以在可用时机会性地使用频谱，并根据需要使用不同的无线协议。全双工无线是一项令人兴奋的新技术，它允许节点在同一频谱上同时发送和接收。尽管取得了重大进展，但现有的全双工无线工作主要集中在窄带生产无线系统上，如Wi-Fi和ZigBee。该项目旨在开发新的系统和算法，以支持认知网络的全双工并支持不同的无线技术。这项研究将被整合到本科和研究生课程中，并广泛传播给研究人员、从业人员、政策制定者、高中生、家长和教师。该项目开发的技术包括：(I)超越窄带并使用新颖的抵消机制在更宽的频段上实现边发送边侦听，(Ii)支持在接收LTE的同时传输Wi-Fi的交叉技术，以及(Iii)通过重新访问上层协议设计将物理层的进步转化为端到端的性能优势。这三个推进将使一个整体的全双工认知无线电平台成为可能。

As new spectrum for data communication becomes available, it is increasingly important to develop cognitive network technologies that can opportunistically use spectrum whenever available and speak different wireless protocols on demand. Full duplex wireless is an exciting new technology that allows a node to send and receive simultaneously on the same spectrum. Despite significant progress, existing work on full duplex wireless focuses on narrowband production wireless systems, such as Wi-Fi and ZigBee. This project aims to develop novel systems and algorithms to embrace full duplex for cognitive networks and support different wireless technologies. The research will be integrated into undergraduate and graduate curriculum, and disseminated broadly to researchers, practitioners policy makers, high school students, parents, and teachers.The project develops techniques that (i) go beyond narrowband and use novel cancellation mechanisms to enable transmit-while-sensing on a wider band spectrum, (ii) support cross technologies that transmit Wi-Fi while receiving LTE and vice versa, and (iii) translate physical layer advances to end-to-end performance benefits by re-visiting upper-layer protocol design. These three thrusts will enable a holistic full duplex cognitive radio platform.
