On May 20, 2015, the paper entitled “LDPC Coded Modulation Schemes with Largely Unequal Error Protection”, co-authored by Giacomo Ricciutelli, Marco Baldi, Nicola Maturo and Franco Chiaraluce, presented by Dr. Giacomo Ricciutelli, has received the “Best Student Paper Award” at the IEEE BlackSeaCom 2015, 3rd International Black Sea Conference on Communications and Networking, held in Constanta, Romania. The paper is another brick in the research activities developed in the Department of Information Engineering with the contribution of PhD students and concerning Physical Layer Security.
More precisely, the authors have considered the case of transmissions over the broadcast channel with confidential messages. In such a scenario, there is the need to implement coding and modulation schemes that are able to achieve unequal error protection. Classical design approaches aim at optimizing the performance over all the protection classes, independently of the separation between them. In this paper, instead, the authors have proposed an original solution which improves the performance over the most protected bits, at the expense of performance over the least protected ones. This allows to design coded modulation schemes with largely unequal error protection. The use of high order modulations has been also considered, and a technique has been presented for studying the performance over each protection class in the asymptotic regime of infinite code length.
On April 9, 2015, the paper entitled “On the applicability of the most reliable basis algorithm for LDPC decoding in telecommand links”, co-authored by Marco Baldi, Franco Chiaraluce, Nicola Maturo and Enrico Paolini, presented by Prof. Franco Chiaraluce, has received the “Best Research Paper Award” at the International Conference on Information and Communication Systems, held in Amman, Jordan. The paper contains some results of a research activity commissioned by the European Space Agency, and concerning the improvement of the error rate performance in the uplink transmission of telecommands to probes, spacecrafts or satellites.
More precisely, the authors have analyzed the performance of two short low-density parity-check codes recently proposed for updating the telecommand standard for space links. They have shown that the most reliable basis decoding algorithm can be efficiently applied to these codes, permitting to achieve a significant coding gain with respect to more conventional iterative algorithms. In particular, in order to maintain limited complexity, the use of a hybrid approach has been suggested, that combines the two decoding procedures in a sequential manner. Thinking in terms of practical implementation, the impact of quantization has been also investigated, by considering two different quantization laws and comparing their performance.
The European BIVEE project ends with the “Excellence” award!
The project BIVEE– Business Innovation in Virtual Enterprise Environments (people involved: Claudia Diamantini, Domenico Potena, Emanuele Storti and Laura Genga of the Knowledge Discovery & Management Group), is a project funded by the FP7 European Program, aimed at supporting SMEs and SMEs networks in innovation development. Nine partners from five European countries worked together for the set up of novel methodologies, frameworks and software for Innovation Management and Governance, according to its motto “Innovating Innovation”.
BIVEE has undergone its final review at the end of February, obtaining the Excellence award from the Commission, an important results for all the partner that have seen honored their commitment and passion. The Commission invited the consortium to exhibit BIVEE success story and results during the ICT 2015 event organized by DG CONNECT on 20-22 October 2015 in Lisbon.
