Abstract

This work investigates the use of received signal strength(RSS) from ISDB-T single frequency networks(SFNs) to localize devices. We employ radiofrequency(RF) fingerprints composed by a RSS circular pattern, i.e. one assumes an antenna that measures the RSS in angular sectors. The device to be located collects the RF fingerprint which is compared against a database of georeferenced patterns to estimate the device location. The presented approach is evaluated using different functions to compare the collected fingerprints with the ones previously stored in a correlation database(CDB). The results show the feasibility of the proposed strategy, achieving an average error of 85.3 m when using 6 single-frequency transmitters in an area of 635 Km².
