CRLBs for WSNs localization in NLOS environment [PDF]
Determination of Cramer-Rao lower bound (CRLB) as an optimality criterion for the problem of localization in wireless sensor networks (WSNs) is a very important issue. Currently, CRLBs have been derived for line-of-sight (LOS) situation in WSNs. However,

Joint Particle Filter and UKF Position Tracking in Severe Non-Line-Of-Sight Situations [PDF]
The performance of localization techniques in a wireless communication system is severely impaired by biases induced in the range and angle measures because of the non-line-of-sight (NLOS) situation, caused by obstacles in the transmitted signal path ...

Polarization Diversity-enabled LOS/NLOS Identification via Carrier Phase Measurements [PDF]
The provision of accurate localization is an increasingly important feature of wireless networks. To this end, a reliable distinction between line-of-sight (LOS) and non-LOS (NLOS) radio links is necessary to avoid degenerative localization estimation ...

Modeling of wide-band MIMO radio channels based on NLoS indoor measurements [PDF]
In this paper, we first verify a previously proposed Kronecker-structure-based narrow-band model for nonline-of-sight (NLoS) indoor multiple-input-multiple-output (MIMO) radio channels based on 5.2-GHz indoor MIMO channel measurements.

Non-line-of-sight propagation in object localization: a survey
Due to the existence of obstacles, none-line-of-sight(NLOS) propagation is common in localization scenes like mines, which causes refraction, reflection, diffraction and scattering of localization signals, leads to the increase of ranging error, and ...
