Abstract
Disclosed is a method of tracking a user's location. The method comprising: receiving coordinate of each of adjacent mobile devices therefrom, estimating a channel environment to select an optimal channel model, calculating distance between the user's mobile device and each of the adjacent mobile devices based on the selected channel model and calculating coordinates corresponding to a current position of the user's mobile device based on the calculated distance.
Claims16
A method of locating a mobile device, the method comprising:
- receiving coordinates of each of a plurality of adjacent mobile devices from the respective adjacent mobile devices;
- estimating a channel environment by using a coherent transceiver of the mobile device to calculate a channel factor based on a signal received from each of the plurality of adjacent mobile devices, and selecting a channel model based on the calculated channel factor;
- calculating a distance between the mobile device and each of the plurality of adjacent mobile devices based on the selected channel model;
- calculating coordinates corresponding to a position of the mobile device based on the calculated distance;
- and
- broadcasting the coordinates corresponding to the position of the mobile device to the plurality of adjacent mobile devices.
