TDD无线通信系统中基于软件的AFC实现

Realization of AFC based on software in TDD system

提出了一种新颖的TDD无线通信系统中AFC实现方式。利用TDD无线通信系统中已有精确定时信号和MCU控制单元,通过程序控制MCU调节压控振荡器的输出频率,从而在未引入过多硬件的基础上以软件方式实现了自动频率控制(AFC),节约了成本。

A new AFC realization method in TDD wireless communication system is presented in this paper.The precise timing signal and MCU control unit which exiting in the TDD radio frequency system are used by the program to adjust the output frequency,thus AFC is realized without introduced so many other hardware,cost is saved.
