| Outline of Final Research Achievements |
To formalize modern coding theory, our research formalized "(spatially coupled) LDPC codes", "sum-product decoding algorithm" and related topics and also developed related theories. For example, we formalized channel capacities over BEC and BSEC, properties of stopping set, and Reed-Solomong codes and Euclidean decoding algorithm. We have organized workshops and open our result through web-sites.
