Optimal Two-Way TOA Localization and Synchronization for Moving User Devices With Clock Drift [PDF]
IEEE Transactions on Vehicular Technology, 2020 In two-way time-of-arrival (TOA) systems, a user device (UD) obtains its position and timing information by round-trip communications to a number of anchor nodes (ANs) at known locations. Compared with the one-way TOA technique, the two-way TOA scheme is
