Abstract
In this paper, we propose a low complexity and robust non-line-of-sight error mitigation technique for positioning applications. It is based on the least trimmed squares estimation and it can reject BSs with large residuals from measured data while using the small ones for final position calculation. In moderate non-line-of-sight environments, our proposed algorithm achieves the best result while keeping the estimation simple. In heavy non-line-of-sight environments, our proposed algorithm achieves a similar performance to a more complex, more accurate techniques. We show that the least trimmed squares estimation can be used to mitigate non-line-of-sight errors under any channel condition.
