摘要：
In this paper we propose a positioning approach based on the time different of arrival (TDOA) algorithm from light emitting diodes to localize mobile targets in indoor environments. The hexagonal lattice alignment of LED transmitters is proposed to reduce the coverage holes and the areas of overlapping radiation. The accuracy of the position estimation is compared to the one in a typical rectangular grid alignment. In addition, an extended Kalman filter is adopted together with the TDOA method to enhance the position estimation performance.
