Abstract
A distance measurement method includes measuring a plurality of integrated signals at a plurality of modulation phase offsets; estimating at least one integrated signal for at least one of the plurality of modulation phase offsets, respectively, to adjust its reception time relative to an integrated signal for another of the plurality of modulation phase offsets; and determining a distance between the target and receiver in accordance with the estimated at least one signal.
