| Research Abstract |
The primary objectives of the COATNET project are fourfold : Optimal design of source/channel coding and signaling techniques, X-layer design optimization by the Turbo principle, Resource allocation based on the results of convergence property analysis of the mutual information exchange, and verification using field measurement data. A commonalty among those objectives is to identify the cause (=transmitted signals) of the observation (=received signals) through extrinsic information transfer (EXIT) analysis, and the final goal is to establish optimal design of distributed networks. We believe that those primary objectives have been achieved, as detailed in 4 : Achievement section.
