Measuring distance using wireless communication |
摘要 |
A method of estimating the distance between a first wireless communication terminal and a second wireless communication terminal includes: receiving a signal at the first terminal, processing the received signal including performing a demodulation operation to produce a demodulated signal; and resolving the demodulated signal into a plurality of components corresponding to different path length components included in the received signal; identifying which of the resolved components corresponds to a shortest path length; and for the identified component, computing a time of travel from the second terminal to the first terminal.
