Patent ID: 8125279

Claim:
A device comprising: a local oscillator (LO) configured to generate a first signal comprising at least one of: timing information; frequency information; phase information; and combinations thereof; a LO error corrector comprising an input, the input configured to receive a second signal comprising at least one of: timing information; frequency information; phase information and combinations thereof, wherein the second signal is used for disciplining the LO, the LO error corrector configured to: if the second signal is unavailable to discipline the LO, discipline the LO using a source that is less accurate than the second signal; upon the second signal becoming at least temporarily available, determine an offset error of the LO relative to the second signal; if the second signal becomes unavailable before the device uses the second signal to discipline the LO on an ongoing basis: correct the offset error of the LO relative to the second signal based on information determined during the second signal's temporary availability; and discipline the LO using a source that is less accurate than the second signal until the second signal becomes at least temporarily available at a subsequent time.
