Abstract
A method to enhance the indoor positioning accuracy by alleviating the effect of multipath distortion is presented. Using this method the line-of-sight (LOS) and non-line-of-sight (NLOS) signals are separated in the frequency domain and multipath induced errors in the pseudorange measurements are decorrelated at a faster rate than under static antenna conditions, resulting in improved positioning accuracy with longer coherent integrations.
