Patent ID: 8022869

Claim:
A method for cross-correlation spur mitigation comprising, with a processor unit: choosing from a plurality of peak measurements, a first peak measurement with a first carrier-to-noise density estimate and a first Doppler offset measurement, and a second peak measurement with a second carrier-to-noise density estimate and a second Doppler offset measurement to form a pair, wherein the first and second peak measurements satisfy a timer check, wherein to satisfy the timer check, an absolute value of a difference in observation times of the first peak measurement and the second peak measurement is less than a timer check threshold; generating one or more electrical signals representing a carrier-to-noise density difference based on the first carrier-to-noise density estimate and the second carrier-to-noise density estimate; generating one or more electrical signals representing a Doppler difference based on the first Doppler offset measurement and the second Doppler offset measurement; comparing the carrier-to-noise density difference to a carrier-to-noise density threshold; and comparing the Doppler difference to at least one Doppler threshold.
