NLOS Mitigation for TOA Location Based on a Modified Deterministic Model

الملخص EN

Wireless location becomes difficult due to contamination of measured time-of-arrival (TOA) caused by non-line-of-sight.

In this letter, TOA measurements seen at base stations are adjusted by scale factors, and a modified deterministic model is built.

An effective numerical solution is proposed to resolve the scale factors and mobile position.

A simulation comparison of four algorithms indicates that the proposed algorithm outperforms the other three algorithms.
