| Research Abstract |
The objectives COATNET-2 has, as an extension of its successor project, COATNET, and three work packages in the project: (1) Wireless Cooperative Communications, including Relaying, (2) Protocol and Scheduling Techniques Design for Distributed Wireless Network, and (3) Design of Practical Transmission Chain and Signal Processing Techniques. The targets of each Work Packages follow the major results of the successor project, COATNET, and the major aim of COATNET-2 is to identify how we can best utilize the information sequence correlation caused by the network. We finally found that the cooperative network, as a whole, can be seen as a distributed source-channel code where regardless of each link's transmission is lossless or lossy. By applying the framework of the lossless/lossy distributed source-channel coding theorem, it has been shown that the proposed network design and processing techniques can achieve much higher efficiency than the conventional techniques.
