作为第五代移动通信系统（5G）的核心技术之一，全双工通信技术能够实现通信系统在同一频率上同时进行无线信号的收发，从而极大地提升频谱利用率，有望实现无线通信系统的容量倍增。全双工通信系统设计与实现的主要难点在于模拟域和数字域自干扰信号消除问题。针对这一问题，介绍了全双工自干扰消除方法，并且对3种典型的全双工无线通信系统设计方案进行分析。

As one of the critical techniques on the fifth-generation mobile communication systems, ful-duplex technique enables the si-multaneous transmission and reception of a device on the same frequency, thus substantial y promoting the spectrum efficien-cy and theoretical y achieving the capacity doubling compared with half-duplex. The main chal enge in designing ful-duplex communication systems comes from the difficulties in cancel ing the self-interference signals in both the analog and digital do-mains. The key technologies for self-interference cancel ation are introduced, fol owed by three typical algorithms analyzed.
