Claim 18:
19. The method of claim 16, further comprising:
scheduling a time synchronization slot for the first transceiver and the second transceiver between the first time-of-departure and the second time-of-departure;
scheduling transmission, from the first transceiver, of a first synchronization signal during the time synchronization slot;
receiving, from the first transceiver, a third time-of-arrival measured by the first clock, the third time-of-arrival corresponding to reception, at the first transceiver, of a first self-receive signal generated by the first transceiver as a first back-coupled reflection of the first synchronization signal;
receiving, from the first transceiver, a fourth time-of-arrival measured by the first clock, the fourth time-of-arrival corresponding to reception, at the first transceiver, of a second synchronization signal transmitted by the second transceiver;
scheduling transmission, from the second transceiver, of the second synchronization signal during the time synchronization slot;
receiving, from the second transceiver, a fifth time-of-arrival measured by the second clock, the fifth time-of-arrival corresponding to reception, at the second transceiver, of a second self-receive signal generated by the second transceiver as a second back-coupled reflection of the second synchronization signal;
receiving, from the second transceiver, a sixth time-of-arrival measured by the second clock, the sixth time-of-arrival corresponding to reception, at the second transceiver, of the first synchronization signal transmitted by the first transceiver; and
calculating a time bias and a propagation delay between the first clock and the second clock based on the third time-of-arrival, the fourth time-of-arrival, the fifth time-of-arrival, and the sixth time-of-arrival.
