最后用这些变量调节本地振荡频率，以跟踪载波频率。
Finally, these judged variables adjust the local oscillating frequency to track the carrier frequency by NCO.
在无线移动通信中，接收机的本地振荡频率和载波频率之间往往存在较大的频率偏差，AFC用于克服此频偏。
In wireless communication system, there is a large frequency bias between carrier frequency and local oscillating frequency. AFC is contributed to eliminate it.
