Radio interferometric geolocation
Miklós Maróti,Peter Volgyesi,Sebestyén Dóra,Branislav Kusý,Andras Nadas,Akos Ledeczi,Gyorgy Balogh,K. Molnar +7 more
TL;DR: A novel radio interference based sensor localization method for wireless sensor networks that does not require any sensors other than the radio used for wireless communication and has an average localization error as small as 3 cm and a range of up to 160 meters.
Journal ArticleDOI
Countersniper system for urban warfare
Akos Ledeczi,Andras Nadas,Peter Volgyesi,Gyorgy Balogh,Branislav Kusy,Janos Sallai,Gábor Pap,Sebestyén Dóra,K. Molnar,Miklós Maróti,Gyula Simon +10 more
TL;DR: In this article, in addition to the overall system architecture, the middleware services and the unique sensor fusion algorithms are described and an analysis of the experimental data gathered during field trials at US military facilities is presented.
Proceedings ArticleDOI
Sensor node localization using mobile acoustic beacons
TL;DR: The acoustic ranging method uses a linear frequency modulated signal that can be accurately detected by matched filtering, which provides longer range and higher accuracy than the current state-of-the-art.

System and methods of radio interference based localization in sensor networks
Akos Ledeczi,Miklós Maróti,Peter Volgyesi,Andras Nadas,K. Molnar,Sebestyén Dóra,Branislav Kusy +6 more
TL;DR: In this paper, a method for radio interference-based sensor localization is presented, which has the steps of creating an interference signal from a first transmitter and a second transmitter, measuring phase offsets of the interference signal received by a first receiver and a secondary receiver, respectively, and determining the locations of the first and second transmitters and the first or second receivers from the measured phase offsets.
Proceedings ArticleDOI
Synchronization of sampling in distributed signal processing systems
TL;DR: The problem is investigated, and signal processing methods are proposed to guarantee the synchronized operation and to reduce the effect of the jitter, based on low-level interpolation and resampling of the sampled signals.
