A non-line-of-sight error mitigation method for location estimation
International Journal of Distributed Sensor Networks, 2017 Because there are always non-line-of-sight effects in signal propagation, researchers have proposed various algorithms to mitigate the measured error caused by non-line-of-sight.

A Non-line-of-Sight Propagation Identification Algorithm in Wireless Sensor Network
IOP Conference Series: Materials Science and Engineering, 2020 Abstract With the rapid developing of communication technology, Wireless Sensor Network(WSN) has been applied in many fields. The accuracy of localization is the vital key to all these applications. In order to mitigate the non-line of-sight(NLOS) influence, we propose a propagation identification algorithm based on Anderson-Darling(AD ...

On the Performance Gain of Harnessing Non-Line-of-Sight Propagation for Visible Light-Based Positioning [PDF]
IEEE Transactions on Wireless Communications, 2020 In practice, visible light signals undergo non-line-of-sight (NLOS) propagation, and in visible light-based positioning (VLP) methods, the NLOS links are usually treated as disturbance sources to simplify the associated signal processing. However, the impact of NLOS propagation on VLP performance is not fully understood. In this paper, we aim to reveal
