afc loop meaning in Chinese

自动频率控制环

In chapter 3 , a carrier synchronization method is put forward , parameters and design of each part of the afc loop are described in detail , at the same time the carrier synchronization unit has been simulated using matlab language and its performance analyzed . simulation results show it efficient
第三章基于综合抗干扰数据传输系统中扩频同步、自适应阵收敛和载波同步的关系,提出一种适合系统并利于fpga实现的载波同步方法,详细阐述了自动频率控制( afc )环路主要部件的参数及电路设计,并对载波同步单元进行了matlab仿真和同步性能分析。
