NLOS identification based on RSS and TOA measurement for indoor UWB localization
, 2020 Ultra-Wideband (UWB) radio is a promising technology that is widely used for indoor localization. However, its positioning accuracy is deteriorated by None Line of Sight (NLOS) signal propagation, which induces a positive bias in range estimation.
