Patent ID: 11340345

Abstract:
Methods, apparatus and systems for wireless object tracking are described. In one example, a described wireless tracking system comprises: a transmitter, a receiver, and a processor. The transmitter is configured for transmitting a first wireless signal using a plurality of transmit antennas towards at least one object in a venue through a wireless multipath channel of the venue. The receiver is configured for: receiving a second wireless signal using a plurality of receive antennas through the wireless multipath channel between the transmitter and the receiver. The second wireless signal differs from the first wireless signal due to the wireless multipath channel and a modulation of the first wireless signal by the at least one object. The processor is configured for obtaining a set of channel information (CI) of the wireless multipath channel based on the second wireless signal received by the receiver, and tracking the at least one object simultaneously based on the set of CI. Each CI in the set is associated with a respective one of the plurality of transmit antennas and a respective one of the plurality of receive antennas.
