Abstract
Examples for performing wireless tracking are described. In one example, a described method comprises: transmitting, by at least one transmitter, a wireless signal through a wireless channel of a venue; receiving, by a receiver, the wireless signal, wherein the received wireless signal differs from the transmitted wireless signal due to the wireless channel and a motion of an object in the venue, wherein neither the at least one transmitter nor the receiver moves with the object; obtaining a time series of channel information (TSCI) of the wireless channel in a time window based on the received wireless signal; generating a plurality of features based on the TSCI over the time window; obtaining a signature map of the venue, wherein each location on the signature map is assigned one or more location signatures representing unique features associated with the location when there is any object at the location; identifying, for each time stamp in the time window, an estimated location of the object in the venue based on the signature map and the plurality of features, and generating a trajectory of the object in the venue over the time window based on the estimated locations of the object.
