Prof. Giorgio Matteo Vitetta,University of Modena & Reggio Emilia and CNIT, Game Theory: Application to Communication Systems

Abstract: In a human community, the goal of each member is to satisfy its own needs through the available environmental resources. Similarly, in a wireless communication network, the terminal of any user tries to satisfy its own requirements, in terms of connectivity, exploiting the resources it is endowed with. Such resources, however, are limited and, at least in part, need to be shared with other users; their physiological shortage raises the problem of establishing fair rules that regulate the sharing among multiple users, each having its own personal goals. This natural similarity between the problem of resource management in a communication system and that of the resource management in a complex social system suggests to adapt the methods, exploited for a long time by economists to tackle the latter problem, to solve the former one. One of the most relevant theoretical methods in this area is probably the so called game theory, which represents a powerful tool to model and solve the above mentioned problems. In this talk, after illustrating some basic concepts of game theory, some of its applications to data communications in wireless ad hoc networks are analysed. In particular, we focus on the problem of coordinating data communications among multiple terminals (acting as data relays), so that reliable multi-hop links can be established.

Dr. Luca Ronga,CNIT, Cognitive Systems

Abstract: Enabled by reconfigurability at physical layer (SDR), Cognitive Radio Networks are providing a stimulating research context for future telecommunication engineering. Initially developed to face the scarcity of radio resources, are becoming a potential solution to several communications challenges such as coexistence, high performances and limited environmental impact of TLC. The talk will expose the basics of Cognitive Radio, its relevant technologies and applications, the potential evolutions and some open issues to stimulate research cooperation among various fields of engineering.

Dr. Carlo Fantozzi,University of Padua, An Example of Hardware/Software Partitioning in SDR Systems, Part 1: the Software

Abstract: In Software-Defined Radio (SDR) systems, the need of attaining flexibility while maintaining high performance pushes physical implementations towards complex architectures with heterogeneous processors: a general-purpose processor (GPP), a Digital Signal Processor (DSP) and a Field Programmable Gate Array (FPGA) are all present in a significant number of cases. With such a diversified lineup of computing resources, the choice of which resource is better suited for each component in the telecommunication system is far from trivial.This is the first of a series of two talks illustrating an example of hardware/ software partitioning for the implementation of a DVB-T2 transmitter on a board with an ARM GPP, a C64x+ DSP and a Virtex4 FPGA. This first talk will introduce the subject, then it will concentrate on protocol/software issues. Hardware issues will be dealt with in the Part2 by Daniele Vogrig on July 1.

Prof. Marina Ruggieri, University of Roma ‘Tor Vergata’, Advanced ICT Infrastructures for Emergency Scenarios

Abstract: The conceivement and deployment of effective ICT infrastructures for emergency applications need a broad and flexible approach to identify suitable technologies and architecture elements. A wise coperation between software and hardware, satellites and terrestrial networks, wired and wireless connections is mandatory to converge towards the proper solution.
The tutorial will drive the audience to explore the ?cooperation? approach and its application in emergency scenarios, providing examples of advanced concepts and applied research achievements. In particular the research activities performed in the above frame at CTIF_Italy (Center for TeleInFrastructures) will be pointed out.

Prof. Enzo Dalle Mese, Università di Pisa and CNIT, Signal Processing in Inverse Synthetic Aperture Radar (ISAR imaging)

Abstract: The ISAR tecnique is based on a suitable signal processing algorithm, in order to increase the radar resolution to obtain a kind of target electromagnetic image. The ‘ISAR kit’ can be realised as a software independent of the radar and for this reason can be clearly understood without particulare knowledge of the radar systems. In this tutorial the ISAR imaging process will be presented from a signal processing point of view. The following arguments will be discussed:- Modelling of the transmitted and received signals- The reflectivity function of the target- Recovery of the reflectivity function from the received signal- Analysis of the resolution attainable- Motion compensation- Superresolution- Future research- Practical example.
