Abstract
A communication device (100) and method therefore for compensating an oscillator (146). The communication device (100) includes a receiver (110) for receiving message information transmitted on a predetermined channel (105), an oscillator (146) having a frequency of operation set by a controller (116) for enabling reception of the message information on the predetermined channel (105), and a decoder (114) for decoding the message information received, and for deriving there from messages and channel quality information. The controller (116) is responsive to the messages derived, for storing the same, and further responsive to the channel quality information derived for generating a compensation signal when the value of the channel quality information exceeds a predetermined value. The compensation signal that is generated by the controller (116) effects shifting of the frequency of operation of the oscillator (146) to center reception of the communication device (100) on the predetermined channel (105).
