带内全双工（IBFD）操作已成为提高无线通信系统和网络吞吐量的一种有吸引力的解决方案。使用IBFD，允许无线终端在同一频带内同时发送和接收。本教程回顾了IBFD无线的主要概念。IBFD运行的最大实际障碍之一是存在自干扰，即调制解调器的发送器对其自己的接收器造成的干扰。本教程调查了广泛的IBFD自干扰缓解技术。还讨论了IBFD无线系统设计和分析中的许多其他研究挑战和机遇。
In-band full-duplex (IBFD) operation has emerged as an attractive solution for increasing the throughput of wireless communication systems and networks. With IBFD, a wireless terminal is allowed to transmit and receive simultaneously in the same frequency band. This tutorial paper reviews the main concepts of IBFD wireless. One of the biggest practical impediments to IBFD operation is the presence of self-interference, i.e., the interference that the modem's transmitter causes to its own receiver. This tutorial surveys a wide range of IBFD self-interference mitigation techniques. Also discussed are numerous other research challenges and opportunities in the design and analysis of IBFD wireless systems.
