Feature-Based Generalized Gaussian Distribution Method for NLoS Detection in Ultra-Wideband (UWB) Indoor Positioning System. (arXiv:2304.11091v1 [eess.SP])
cs.LG updates on arXiv.org arxiv.org
Non-Line-of-Sight (NLoS) propagation condition is a crucial factor affecting
the precision of the localization in the Ultra-Wideband (UWB) Indoor
Positioning System (IPS). Numerous supervised Machine Learning (ML) approaches
have been applied for NLoS identification to improve the accuracy of the IPS.
However, it is difficult for existing ML approaches to maintain a high
classification accuracy when the database contains a small number of NLoS
signals and a large number of Line-of-Sight (LoS) signals. The inaccurate
localization of the target node …
