An Rx selection for reducing spatial variation in TOA localization accuracy

In this paper, we propose a method to select a set of receiving stations (Rxs) from multiple Rxs candidates in a certain monitoring area for the Time Of Arrival (TOA) localization. This proposed method focuses on the fact that the TOA localization accuracy varies depending on the position of the Rxs. We propose a Rxs selection method based on distances between Rxs so that the Rxs are selected evenly. In addition, to tackle the problem that the accuracy deteriorates at the contour of the monitoring area, we propose a method to prioritize the Rxs at the contour of the monitoring station as well. By simulation, we show the effectiveness of the proposed method.
