| Outline of Final Research Achievements |
The goal of the STAR-CODE project is to create efficient communication concepts/technologies for multiterminal nodes based on the recent advances in network information theory and coding theory, where the network itself expresses a structure of coding schemes. Example of applications include disaster-area communication systems, universal wireless access in rural areas, sensor networks and vehicle-to-vehicle communications. The outcomes include new algorithms, theorems, coding schemes to improve the data throughput, reduce the power use, and increase the reliability of star-structured network topologies.
In summary, the results are: (1) new wireless network capacity bound for networks with multiple relays and side information, (2) new decoding technique for multiple multiway relay, (3) explicit error-floor analysis for finite-length setting, (4) induced degree distribution due to Rayleigh fading channels, (5) optimal degree distributions.
