Abstract
A system for adjusting the frequency of transmissions between a base station and a mobile station. The mobile station detects the frequency of the signal received from the base station, determines whether the signal was received from the current base station and adjusts the output signal of a local crystal-controlled reference oscillator in accordance with the difference between the frequency of the output signal and the frequency of the received signal.
