A New Method of D-TDOA Time Measurement Based on RTT

open access: yesMATEC Web of Conferences, 2018
In this paper, a novel difference-time difference of arrival (D-TDOA) time measurement method based on round-trip transmission (RTT) is proposed. The accuracy of time measurement is critical for high accuracy positioning, yet the traditional time ...
