在本文中，我们提出了一种用于 5G 无线网络的实时全双工无线电系统。全双工无线电能够在无线电资源有限的高流量需求环境中开辟新的可能性。然而，在实际无线环境中实现全双工无线电的一个关键问题是能够消除自干扰。为了克服自干扰挑战，我们在软件定义的无线电平台上对我们的设计进行了原型设计。该设计将基于双极化天线的模拟部分与实时运行的数字自干扰消除器相结合。原型测试结果证实，所提出的全双工系统的吞吐量比半双工系统高约 1.9 倍。本文最后讨论了研究人员在寻求最可行的全双工通信解决方案时仍然面临的实施挑战。
In this article, we present a real-time full duplex radio system for 5G wireless networks. Full duplex radios are capable of opening new possibilities in contexts of high traffic demand where there are limited radio resources. A critical issue, however, in implementing full duplex radios in real wireless environments is being able to cancel self-interference. To overcome the selfinterference challenge, we prototype our design on a software-defined radio platform. This design combines a dual-polarization antenna-based analog part with a digital self-interference canceler that operates in real time. Prototype test results confirm that the proposed full duplex system achieves about 1.9 times higher throughput than a half duplex system. This article concludes with a discussion of implementation challenges that remain for researchers seeking the most viable solution for full duplex communications.
