چکیده

A Non-light-of-sight (NLOS) mitigation approach based on GBSBEM was proposed in this paper. The main idea is to model the NLOS errors to the elliptical model and mitigate them with a novel method. At the first step, the semi-minor of GBSBEM is estimated, then a way to restrain the NLOS errors with the help of the semi-minor is used. When the semi-minor can not be estimated, an optimization method based on GBSBEM pdf is presented. The method has a good effect to reduce the NLOS error, especially when the NLOS effect is notable.

IMU-Aided Dual-Frequency RFID Based Localization in LOS/NLOS Hybrid Environment

The mitigation of NLOS (non-line-of-sight) propagation conditions is one of main challenges in wireless signals based indoor localization. When RFID localization technology is applied in applications, RSS fluctuates frequently due to the shade and multipath effect of RF signal, which could result in localization inaccuracy. In particularly, when tags carriers are walking in LOS (line-of-sight) ...

NLOS mitigation in indoor localization by marginalized Monte Carlo Gaussian smoothing

One of the main challenges in indoor time-of-arrival (TOA)-based wireless localization systems is to mitigate non-line-of-sight (NLOS) propagation conditions, which degrade the overall positioning performance. The positive skewed non-Gaussian nature of TOA observations under LOS/NLOS conditions can be modeled as a heavy-tailed skew t-distributed measurement noise. The main goal of this article ...
