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.
Claims16
A ranging method, executed in a ranging device, comprising:
