摘　　要：作为第五代移动通信网络(5G)的关键技术之一,同频同时全双工成为如今学术界研究的热点问题。理想情况下,全双工通信模式能实现频谱效率的倍增,大大提高信息传输速率、信道容量等。但是,要真正实现全双工还存在很多待解决的问题。针对目前国内外研究人员在全双工中继协作通信技术方面的研究,总结全双工中继协作通信的优势和面临的几个关键问题,着重对全双工中继协作通信技术出现的自干扰问题进行分析描述,并对现存的自干扰消除方案进行了介绍和技术点分析。As one of the key technologies of the fifth generation network communication（5G）,the same frequency at the same time full-duplex technology is now the hot topic of academic research.In the ideal case,full-duplex communication mode can achieve the spectral efficiency of the multiplier,improving the information transmission rate,channel capacity greatly,but there are still many problems to be solved to achieve full-duplex.In view of the present research in full duplex relay cooperative communication technology of the researchers at home and abroad,we summarize several advantages and key problems of full-duplex technology,In particular,the self-interference problem of full-duplex relay communication tKecehyn woloorgdy si：s analyzed,and the existing self-interference cancellation schemes are introduced and analyzed.
