Abstract
A system and method for determining the distance between two wireless network devices is disclosed. The present system utilizes a plurality of pseudo-spectrums to create a more accurate final pseudo-spectrum. The pseudo-spectrums are graphs, where peaks in the graphs are indicative of the magnitude of the signal received at a certain distance. In some embodiments, the pseudo-spectrums are generated using the MUSIC algorithm. The final pseudo-spectrum is generated by performing a mathematical operation on corresponding elements in each pseudo-spectrum. This mathematical operation may include multiplication and normalization. The final pseudo-spectrum provides a more accurate indication of the distance between the devices than can otherwise be achieved.
