Abstract:
Automatic frequency controllers, automatic frequency control methods, wireless communication devices, and/or wireless communication methods are provided. The automatic frequency controllers for correcting a frequency offset between a base station and a terminal includes at least one processor communicatively coupled to a memory and configured to execute computer-readable instructions stored in the memory to obtain a phase estimate from a reference signal received from the base station; classify a downlink channel as a High Speed Train (HST) channel or a non-HST channel based on the phase estimate; adjust a loop gain according to the classified downlink channel; calculate a phase error based on the phase estimate and the loop gain; correct the frequency offset using the phase error; and communicate with the base station after correcting the frequency offset.

Claim (Index 4):
The automatic frequency controller of  claim 3 , wherein the wireless channel classifier comprises:\n a moving mean calculator configured to calculate a moving mean of an absolute value of the phase estimate; and a moving variance calculator configured to calculate a moving variance of the absolute value of the phase estimate.
