Viewing sector optimisation for indoor localisation using multi-lateration with unilateral nodes deployment

摘要

Viewing sector optimisation allows reaching a maximum available localisation accuracy in indoor environments using optimal estimators. In this study, the authors provide such an optimisation for multi-lateration by employing the unbiased finite impulse response (UFIR) filtering technique, which ignores noise and initial values. The authors consider the unilateral deployment of anchor nodes and show, both theoretically and experimentally, that the optimal angle of arrival is zero, optimal viewing angle is
