Claim 0:
1. An electronic device comprising:
memory circuitry;
interface circuitry; and
processor circuitry;
wherein the processor circuitry is configured to:
transmit, to a plurality of electronic reference devices, a first signal, the first signal having a pulse width below a threshold;
receive a plurality of second signals from the plurality of electronic reference devices comprising original second signals from each of the plurality of electronic reference devices and reflections of the original second signals;
filter the reflections of the original second signals from the plurality of second signals leaving filtered received second signals;
determine a round-trip time of the filtered received second signals;
determine, based on the round-trip time of the filtered received second signals and at least one predetermined time period, a time of flight of each of the filtered second signals;
determine, based on each time of flight, distances between the electronic device and each electronic reference device of the plurality of electronic reference devices, the distances comprising a first distance, and a second distance;
obtain, reference positions of the plurality of electronic reference devices;
associate the first distance with a first candidate electronic reference device having one of the reference positions;
associate the second distance with a second candidate electronic reference device having one of the remaining reference positions;
determine, based on the associations, one or more candidate positions of the electronic device; and
determine, based on the distances, the one or more candidate positions, and the obtained reference positions, a position of the electronic device.
