ABSTRACT:
A method of frequency tracking based on recovered data, for use in an automatic frequency control subsystem at the receiver of a mobile station, is disclosed. The frequency tracking mechanism derives frequency error information from the recovered data to determine the adjustment needed at the mobile station's local voltage controlled oscillator in order to track the frequency of the base station.
