Abstract
Improvements associated with determining a location of a station device are described. According to one improvement, a method is performed by a network device. The method includes receiving a response packet from a station device, multiple times, as received signals by switching between a plurality of antennas of the network device during reception of each occurrence of the response packet. The received signals are converted to corrupted orthogonal samples. The response packet is received from the station device a final time as a final response packet via a single antenna of the plurality of antennas. Ideal orthogonal samples are re-generated based at least in part on the final response packet. Signal phase information, embedded in the corrupted and ideal orthogonal samples, is converted into estimated locations of the station device.
