摘要
同时频全双工(CCFD)技术能倍增无线信道吞吐量,提高频谱资源利用率,保证无线传输中的实时反馈与自动控制,使5G在未来工业互联网和物联网中发挥重要作用。首先表述了CCFD的基本通信原理,而后用频分双工算法和方向图函数分析了在天线阵列中用波束赋形方式消除天线中的强自干扰过程,同时还分析了射频干扰消除和数字干扰消除的简单方式,为设计5G终端天线系统提供了有益参考。
CCFD technology can double the throughput of the wireless channel, improve the utilization of spectrum resources, ensure re- al-time feedback and automatic control in the wireless transmission, so that 5G will play an important role in the future indus- trial Internet and loT. It first expresses the basic principles of CCFD, analyzes the process of eliminating strong self interference in antenna with beamforming methods. It also analyzes the simple way to RF interference cancellation and digital interference cancellation to provide a useful reference for design of 5G terminal antenna system.
