Maximum Correntropy Criterion for Robust TOA-Based Localization in NLOS Environments [PDF]

open access: yesCircuits, systems, and signal processing, 2020
We investigate the problem of time-of-arrival (TOA)-based localization under possible non-line-of-sight (NLOS) propagation conditions. To robustify the squared-range-based location estimator, we follow the maximum correntropy criterion, essentially the ...
