Abstract

In one embodiment, a vehicle side target location method includes receiving a request, via a first wireless connection, for the vehicle to travel to a location, in response to the vehicle being less than a predetermined distance from the location, receiving RF packets, via a second wireless connection having a multiple antenna radio frequency (RF) transceiver having an identification (ID), from a target at the location, identifying packets based on the ID of the RF transceiver, extracting channel state information (CSI) from received signals associated with the identified packets, determining an amplitude difference of subcarriers of the received signals between each of the multiple antennae, filtering noise of the amplitude difference of subcarriers based on subcarrier selection to obtain multiple robust amplitude difference signals, and feeding the multiple robust amplitude difference signals to a classifier to obtain a side of the vehicle associated with the location of the target.
