摘要
在5G通信研发中,同时同频全双工(CCFD)作为提高频谱效率的关键技术之一,需要克服的重要问题就在于自干扰的消除。文章研究了关注较少的数字消除方式,提出了基于信道估计的自适应滤波方案,并对自干扰信道估计及自适应滤波这两个重要过程作出了分析,最后通过MATLAB实验仿真验证了该方案的消除性能。
In the research and development of 5G communication, the co-time co-frequency full duplex（CCFD） is one of the key technologies to improve the spectrum efficiency. The important problem to be overcome is the elimination of self-interference. In this paper, the less concerned digital elimination method is studied, the adaptive filtering scheme based on channel estimation is proposed,and the two important processes of self-interference channel estimation and adaptive filtering are analyzed. Finally, the performance of the scheme is verified by Matlab simulation.
