Identification of NLOS and Multi-Path Conditions in UWB Localization Using Machine Learning Methods

Applied Sciences, 2020
In ultra-wideband (UWB)-based wireless ranging or distance measurement, differentiation between line-of-sight (LOS), non-line-of-sight (NLOS), and multi-path (MP) conditions is important for precise indoor localization.

IR-UWB Detection and Fusion Strategies using Multiple Detector Types

, 2016
Optimal detection of ultra wideband (UWB) pulses in a UWB transceiver employing multiple detector types is proposed and analyzed in this paper. We propose several fusion techniques for fusing decisions made by individual IR-UWB detectors.
