Ultra-wideband (UWB) positioning systems often operate in a non-line-of-sight (NLOS) environment. NLOS propagation has become the main source of ultra-wideband indoor errors. As such, how to identify and correct errors key problem that must be solved high-accuracy technology. This paper firstly describes influence path on localization accuracy generation method signals, secondly classifies analyzes currently available algorithms for identification error suppression. For NLOS, residual...
This study presents a novel approach to indoor positioning leveraging radio frequency identification (RFID) technology based on received signal strength indication (RSSI). The proposed methodology integrates Gaussian Kalman filtering for effective preprocessing and time-distributed auto encoder-gated recurrent unit (TAE-GRU) model precise location prediction. Addressing the prevalent challenges of low accuracy extended localization times in current systems, method significantly enhances RSSI...
