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 path. We present issues of an new High Resolution Direct Path Tracker (HRDPT) architecture, that allows an efficent hardware implementation of a high resolution method for multi path mitigation, and demonstrate first results.
