Patent ID: 7974585

Claim:
A device comprising: an oscillator operable to generate an oscillating signal; a transceiver operable to receive said oscillating signal and a first reference signal, wherein said transceiver is operable to generate a carrier wave frequency operable to tune to a data signal being received; and a processor operable to determine a first estimated frequency error based on said oscillating signal and said first reference signal, and wherein said processor is further operable to apply a frequency of a second reference signal as a frequency of said carrier wave if said first estimated frequency error is less than a threshold and further operable to select a frequency of a third reference signal if said first estimated frequency error is greater than said threshold, and wherein said processor performs a binary search for a proper reference signal if selection of said frequency of said third reference signal generates an unsatisfactory result, wherein said binary search is based on a second estimated frequency error associated with said third reference signal.
