TDOA Location Accuracy Experiment

open access: yesJournal of Physics: Conference Series, 2019
Abstract TDOA-based wireless signal location technology has been extensively used in engineering applications. Due to the lack of quantitative TDOA location accuracy index benchmark, there is the absence of reference basis in the development of TDOA application system indicators and performance evaluation.
