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.
Claims12
A ranging method, executed in a ranging device, comprising:
- 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, wherein each parameter set comprises at least one parameter related to the statistical value of the rising time of the 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.
A location method, executed in a location device, comprising:
- obtaining distances between the location device and objects;
- and
- determining a location of the location device according to the distances;
- wherein each distance between the location device and the object is obtained by following steps:
- 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, wherein each parameter set comprises at least one parameter related to the statistical value of the rising time of the 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.
