derivation of a range information model for design and analysis of wideband ranging systems based on energy detection; [J3]
development of low-complexity ranging algorithms with optimal energy detection for localization with soft-decision and hard-decision ranging;
Radio-frequency Identification, Localization, and Tracking

introduction of blind techniques for the selection of representative observations in sensor radars; [J4]
development of a methodology for design and analysis of sensor radars by jointly considering (i) network setting, (ii) propagation environment, (iii) waveform processing, (iv) observation selection, and (v) localization algorithm; and [J1]

PATH - PAssive Tracking of people and things for physical beHavior analysis
Horizon 2020 - MSCA Global Fellowship
MIT and University of Ferrara
June 2016 -
The main goal of PATH is to define a new paradigm for the behavior analysis of physical targets (e.g., people and things), by tracking their positions and dynamics with minimal implementation cost, maximal privacy preservation, and intrinsic secrecy protection. Without relying on any targets’ device and without deploying any dedicated wireless source, PATH enables the detection, localization, and tracking of targets that do not participate in the localization process and integrates such capabilities in infrastructures for the Internet of things. This is essential for several applications relying on behavior analysis, such as crowd counting and flow monitoring. The objectives of PATH are: (i) to develop a framework for system design and analysis, as well as to derive fundamental limits; (ii) to devise advanced techniques for detection and exploitation of networks of opportunity (i.e., networks not intended for localization and covering the operating environment); (iii) to develop inference techniques based on wireless networks properties for intrinsically secure tracking; (iv) to recognize new patterns related to targets dynamics based on signal feature extraction; (v) to establish a proof-of-concept for an industrial-driven use case.
SELECT Smart and Efficient Location, Identification, and Cooperation Techniques
EU Framework Programme FP7
The objective of the SELECT project is the design of a cheap smart wireless network, composed of several wireless cooperating microsystems where the detection, identification, and tracking of objects are integrated, going beyond the limitation of the existing techniques for automatic identification (AutoID) and Real Time Location Systems (RTLS). Limitations are for instance, the unavailability of location systems for semi-passive tags, inflexible, cabled network structures of RTLS, the missing compatibility to prior systems and the missing unification of the above functionalities. Envisioned technologies to overcome these limitations include radio frequency identification (RFID), ultra-wideband (UWB) radio and radar as well as up to date data fusion.
The focus of SELECT is in the area of intelligent transportation and intelligent manufacturing and, in particular, the Supply Chain Management (SCM), that involves the transportation of goods outside and inside the manufacturing facilities. The objective of SELECT is to offer a radical new approach to address some important needs in this arena.
GRETA - GREen TAgs and sensors with ultrawideband identification and localization capabilities
Italian Ministry of Education, University and Research PRIN
GRETA aims at studying a distributed system for identification, localization, tracking and monitoring in IoT indoor scenarios, where the tags are:
localizable with sub-meter precision even in indoor scenarios ⇒ ultra-wideband (UWB) localization techniques
without batteries ⇒ energy harvesting + passive backscattering transmission
made with recyclable materials, to be integrated in goods, clothes and packing ⇒ “green electronics” with recyclable, possibly organic materials
