ABSTRACT
We present a SDR-based indoor localization system for mobile devices that relies on fingerprint approaches of ambient FM and DVB-T signals. Unlike conventional indoor localization systems [1][2], our system can 1) perform data normalization, allowing cross platforms and antennas for localization while maintaining under 0.5 meters error; 2) be used with commercial off-the-shelf (COTS) mobile devices and SDR antennas, making the system more practical and useful in real scenarios; and 3) have the potential of making use of other signals as long their frequencies are within the range detected by SDR.
