Titel
System issues for time synchronization in Real Time Localization Systems with multi path mitigation
Abstract
Accurate localization systems, based on the measurement of the time of flight of a signal between radio devices, also known as Real Time Location Systems (RTLS) are becoming increasingly important especially in indoor applications. Due to severe multi path conditions, the largest problem for those RTLS systems is to detect the time of arrival of signals traveling over the direct line of sight (DLOS) path. High Resolution (HR) techniques may support detection of the LOS signal. We present ideas for efficient implementation of such a technique and demonstrate HR-performance by presenting results of practical measurements experiments.
