碩士 === 國立中正大學 === 通訊工程研究所 === 101 === In an indoor environment, where GPS signal is not available, localization typically relies on triangulation or fingerprint (or radio map) algorithms. These algorithms require the availability of three or more anchor points (or reference points). In this thesis, we propose a novel localization algorithm, which can derive the location of moving users with high accuracy based on measuring the technologically feasible displacement vector in the environment where only one anchor point is needed. The proposed localization algorithm can locate a user in a 3-dimensional space and has been tested on a smartphone to verify its feasibility and accuracy.
