带内全双工（IBFD）技术允许设备同时在相同频率上进行发送和接收，从而实现独特的系统功能和网络架构。虽然以前被认为是不可能的，但这种能力现在可以用于优化各种通信系统（包括5G新无线电）拥挤频谱内的资源共享。这些IBFD系统的潜力只能实现，如果每个设备采用了足够数量的自干扰消除技术，以确保其接收器不饱和。本教程调查提供了迄今为止最全面的这些技术集合，并讨论了如何在典型收发器的不同域中实现所有这些技术。此外，一个新的IBFD系统研究的结果，提出了50多个演示通信系统与80多个不同的测量方案。然后，各种系统参数被组合成一个新的品质因数，该品质因数可用于推动未来的研究，并加速将IBFD技术纳入即将推出的无线标准。
In-band full-duplex (IBFD) technology can enable unique system capabilities and network architectures by allowing devices to transmit and receive on the same frequency at the same time. While previously considered impossible, this ability can now be used to optimize resource sharing within the crowded frequency spectrum for various communication systems, including 5G new radio. The potential of these IBFD systems can only be realized if each device incorporates a sufficient number of self-interference cancellation techniques to ensure that its receivers do not saturate. This tutorial survey offers the most comprehensive collection to date of these techniques and discusses how all of them can be implemented within the different domains of a typical transceiver. In addition, the results of a novel IBFD system study are presented for more than 50 demonstrated communication systems with more than 80 different measurement scenarios. The various system parameters are then combined into a new figure of merit, which can be used to propel future research and accelerate the inclusion of IBFD technology within an upcoming wireless standard.
