Abstract: A ranging method, executed in a ranging device, comprising steps of: obtaining a trip time of a received wireless signal, wherein the received wireless signal is a wireless signal from an object; calculating a statistical value of a rising time of the received wireless signal; correcting the trip time according to the statistical value of the rising time; and estimating a distance between the object and the ranging device according to the corrected trip time.

Abstract: A ranging method, executed in a ranging device, comprising steps of: among a plurality of parameter sets under a specific constraint, selecting one parameter set which minimizes a statistical value of a rising time of a received wireless signal; obtaining a trip time of the received wireless signal, wherein the received wireless signal is a wireless signal from an object; and estimating a distance between the object and the ranging device according to a corrected trip time, wherein the statistical value of the rising time of the received wireless signal corrects the trip time of the received wireless signal to generate the corrected trip time.
