SWAN (1998-2000)
DUNE has coordinated several European enterprises and universities in the development of a underwater acoustic communication network to be employed in shallow waters and able to operate in an environment affected by severe multipath. Blind techniques for channel equalization have been analysed and OFDM (Orthogonal Frequency Division Multiplexing) methods have been investigated. The proposed blind techniques have been validated by real data collected in campaigns carried out on the oceanic shelf near the Dutch coasts.
SATURN (1999-2002)
In the fourth framework program of the European Commission, DUNE was in charge of the coordination (management and scientific supervision) of several academic institutions and industrial companies for the theoretic-experimental project on digital telecommunications, positively accomplished in 2002. The work produced innovative results in the development both of new processing methods and of new models of radio propagation for multiple antenna systems. Project results have been disseminated through the participation to many international events, as well as through the publication of more than one hundred papers on scientific magazines and journals.
ROMANTIK (2002-2005)
In the fifth framework program of the European Commission, DUNE participated, with academic corporations and European companies, to the ROMANTIK theoretical-experimental project on digital telecommunication networks. The work has produced innovative results on the development of peer-to-peer communication methods and of processing methods for UMTS that are to submitted to the 3GPP (3rd Generation Partnership Project) UMTS standardisation board. Results have been spread trough international events as well as through the publication of many papers on scientific magazines and journals.
STARMATE (2000-2003)
In the frame of the IST (Information Societies Technologies) of the European Commission, DUNE collaborated with companies and French, Spanish and German research centres for the development of a support system for the maintenance of complex industrial equipment. The systems tele-transfers to the operator technical information aimed at simplifying work and minimizing errors: the user, by wearing a multimedia helmet designed by DUNE, is enabled, through optical paths projected directly on the real scene, to locate the element on which to operate, and in the meantime is enabled to receive audio and video information on the operations to be performed. DUNE has been responsible for the communication system between the operator and the supervision centre.
SENSI (2000-2002)
In this project, coordinated by MIUR (Ministry of Instruction, University and Research), DUNE participated in the development of a telemetry measurement system, which integrates the active vision module (implemented through laser range finder) with the passive vision module. DUNE was responsible for the study and the implementation of a passive system including a couple of cameras in stereo mode and a real-time computing subsystem, implemented by 8 Hammeread DSP (ADSP21160). During the work original algorithms have been developed for processing the scene and selecting homologous portions on the two stereoscopic images.
TOMPACO (1999-2002)
In the project, coordinated by MIUR (Ministry of Instruction, University and Research), DUNE developed an original methodology to estimate the sea temperature distribution of large coastal areas, at low and medium sea depths, through the development of acoustic methods based on passive tomographic inversion (see a result). In opposition to previous methods, the employed approach exploits the acoustic emission of opportunity ships (not cooperating), requiring neither dedicated acoustic sources, nor the knowledge of basin geo-morphologic parameters (eg. sounding, source distance and depth, etc.). The developed methodology has been applied to acoustic data gathered during a measurement campaign (Portugal), providing correct results of temperature estimation and distance of ship of opportunity utilized as (unknown) acoustic source. The work results have been spread through the participation to a number of international events and publications on scientific magazines. Further references about TOMPACO are here (ref1, ref2. ref3)
MFE (2003-2004)
The measurement system of the Electrical Phase is composed by a device producing a harmonic signal with a broad frequency band (10 -200 MHz). This signal is used to test a circuit for phase measurements. The circuit output signal is sent to the MFE which can measure with high accuracy the phase difference between the produced and the input signals. In order to fulfil the measurement requirements, the system employs radio frequency electronic circuits, designed and implemented by DUNE, and a computing system based on DSP, provided by the firm with original algorithms for phase measurement. The MFE system can be employed in a number of applications, among which very high accuracy distance measurement by metrological laser. The system has been co-financed by FILAS (Development Holding Company for Lazio Region) in the framework of LR 23/86 (modified in LR 10/01). A paper related to the MFE activity is (here).

Ongoing projects
WINSOC:
Wireless Sensor Networks with Self-Organization Capabilities for Critical and Emergency Applications (2006-2008)Application area: Wireless communication
Submitted to: European Commission, Framework Program VI
The main problems in designing sensor networks are the high reliability required to the whole system and the potential unreliability of the single sensor, beside critical issues related with the scalability and congestion around the sink or control nodes. The most common approach available today consists in adapting the protocol stack of communication networks to sensor networks; however, requirements and constraints of sensor networks are so different from communication networks. The key idea of WINSOC is precisely the development of a totally innovative design methodology. WINSOC project envisages the development of sensor nodes based on the biologically inspired systems. The target of WINSOC is to design, build and test a prototype of a totally inno-vative type of bio-inspired, scalable, self-organising wireless sensor network, not based on layered protocols (e.g.OSI stacking), thus avoiding the associated signal overhead, complexity and power consumption. The pursued bio-inspired approach goes beyond the cross-layer design, enabling both the design of a new type of very simple sensor and the existence of emergent behaviours of the network: i.e. the estimation capabilities of the network as a whole outperform those of the sensors, but with no centralised data-fusion or information sinks node. WINSOC paradigms aim at solving or substantially mitigating the problems and drawbacks associated with the existing or under development sensor networks.

SURFACE: Self-Configurable Air Interface (2006-2008)
Application area: Wireless Communication
Submitted to: European Commission, Framework Program VI
This project aims at studying and evaluating the performance of a novel generalised air interface for the forthcoming 4G systems, capable of self-reconfiguring in order to satisfy global network QoS (Quality of Service) requirements, based on channel and traffic knowledge. The project considers Multiple Input Multiple Output (MIMO) technologies as an option and develops a general framework that includes as specific cases standardised access technologies like DS-CDMA, MC-CDMA and OFDM to develop a physical layer, completely reconfigurable to match the global instantaneous, but imperfect, channel state, mobility, traffic information and terminal capabilities. The activity is foreseen to positively impact on the standardisation process of WiMax (IEEE 802.16) and UMTS evolution.
