加州大学全双工从自干扰消除到无线网络安全的研究之旅
A Research Journey of Full-Duplex at University of California from Self-Interference Cancellation to Wireless Network Security
摘要：
本文概述了美国加州大学河滨分校在过去十年中对全双工技术的研究。这项研究最初集中在自干扰（SI）消除，然后转移到全双工的应用，以提高网络的频谱效率，并在近年来进一步发现全双工的无线网络安全的潜力。对SI消除的研究已经产生了基于硬件的SI消除结果和一些先进的理论架构，这些理论架构显示出希望，但尚未通过先进的硬件实现进行测试。全双工在ad hoc、认知和蜂窝网络中用于优化频谱效率的应用已经展示了如何在全双工节点之间、在其天线波束空间中以及在多个子载波上优化功率分配。全双工还被发现对于提高合法用户之间的保密能力以防止窃听非常有益。在全双工为网络安全提供的新能力中，有一种有效的防窃听信道估计方案，这对于没有全双工的节点是不可能的。
英文摘要：
This article provides an overview of research on full-duplex at the University of California, Riverside, in the past decade. This research was initially focused on self-interference (SI) cancellation, then moved to applications of full-duplex to improve network spectral efficiency, and in recent years advanced to discover full-duplex's potentials for wireless network security. The research on SI cancellation has resulted in both hardware-based SI cancellation results and some advanced theoretical architectures which show promises but are yet to be tested via advanced hardware implementations. The applications of full-duplex for optimized spectral efficiency in ad hoc, cognitive and cellular networks have shown how to optimize power allocation among full-duplex nodes, in their antenna beamspace and over multiple subcarriers. Full-duplex has also been found to be highly beneficial for improving secrecy capacity between legitimate users against eavesdropping. Among the new capabilities that full-duplex provides for network security is an effective anti-eavesdropping channel estimation scheme which is not possible for nodes without full-duplex.
