Development and Prospect of Ultra-Wideband Localization Research and Application

Ultra-Wideband(UWB) has the ability of achieving the better ranging and localization precision than current wireless system.The research and application of UWB localization are studied on this paper,in which the main topics include the different UWB localization methods like TOA/TDOA(Time/Time Difference of Arrival),multipath delay estimation theory,non-light-of-sight localization,cooperative localization,MB-OFDM(Orthogonal Frequency Division Multiplexing) and other ultra-wideband signals localization.Then its development and actuality are discussed in details.The existing problems and several future valuable research directions are summarized finally.
