Abstract
Correcting a time of reception of a data packet is disclosed. A radio-frequency input is converted to a data-output signal. A data clock is recovered from the data-output signal. A phase offset is measured between the data-output signal and the data clock. A time of reception is corrected based at least in part on a timestamp. The timestamp is a sampled value of a counter at a time of reception of a data packet and the phase offset. The time correction can be used to calculate a distance estimate.
