Project Structure & Workpackages description

The project was structured into seven complementary Work Packages (WP) related as shown in the PERT diagram to the right. The split of functionalities ensured complementarities of activities and partner’s background/know-how. The project has been led by Dr. Alain Mourad (Samsung UK), DAVINCI Project Coordinator.

 

  • WP1 "Management and Coordination":
    The primary objective and responsibility of this workpackage was to ensure consistency of actions throughout the entire project. This workpackage was also the interface with the EU commission representatives and other FP7 projects.
    Workpackage Leader: Dr. Alain Mourad (SEUK)


  • WP2 "Performance Analysis and Evaluation":
    WP2 focused on possible uses of DAVINCI technology by IMT-Advanced Systems (e.g. IEEE 802.16m, 3GPP-LTE). As such, WP2 analysed requirements from IMT-Advanced candidates and thus ended up with constraints and targets used in WP4, WP5 and WP6. Besides, some of the best solutions developed jointly by WP4 and WP5 have been evaluated and selected through complexity evaluation and feasibility by WP6.
    Workpackage Leader: Dr. Alain Mourad     (SEUK)

     

  • WP3 "Integration and Demonstration":
    This activity encompassed realistic implementation of some advanced solutions developed within the project, as well as its demonstration within an IEEE 802.11n platform.
    Workpackage Leader: Dr. André Bourdoux (IMEC)

     

  • WP4 "Advanced Channel Coding":
    WP4 focused on the development of new structures for non-binary LDPC codes with the objective of approaching the theoretical error correction limits at small codeword lengths, and high spectral efficiency. Moreover, the proposed codes have been adapted in order to incorporate incorporating rate and block length adaptability. These codes have been then verified by the rest of work packages both in terms of performance and implemtantion complexity.
    Workpackage Leader: Prof. David Declercq     (ENSEA)

     

  • WP5 "Link Level Technologies":
    The main objective of this work package has been to develop new techniques that are able to take advantage of the new reliability information (soft-output) about the channel symbols to perform the ancillary PHY functions: carrier/timing synchronization and channel estimation/compensation (equalization). In addition, techniques such as H-ARQ or rate matching have been also studied in order to optimize them to the DAVINCI non-binary LDPC codes.
    Workpackage Leader: Prof. Marco Luise     (WISER)

     

  • WP6 "Adequacy Algorithm Architecture":
    The goal of this WP was to perform a coherent interface between WP4 (nb-LDPC definition), WP5 (link level definition) and the conception of a FEC that will be included in WP3. In fact, the experience shows that in the domain of FEC, the code definition and the architecture conception are closely related and have to be defined jointly.
    Workpackage Leader: Prof. Emmanuel Boutillon (UBS)

     

  • WP7: Exploitation and Dissemination:
    In order to promote DAVINCI technology, WP7 has carefully looked at those standards and/or regulatory bodies where possible contributions could be made. Moreover, besides publication into international conferences or journals, specific workshops and seminars have been arranged to disseminate the project results in the scientific community and also to raise the interest of industry.
    Workpackage Leader: Dr. Stephan Pfletschinger     (CTTC)
