Effect of Particle Filter to the Finger Print with wide coordinate interval

Currently, research is being conducted on location estimation using wireless LAN access points. In this research, we apply a particle filter, which is one of the time series filters, to examine the design method of its parameters and evaluate its accuracy. As a result of adjusting the parameters in the proposed method, the estimation error could be reduced. It was also confirmed that the proposed method can improve the accuracy more than the conventional method even if the DB coordinate interval increases.
