| Outline of Final Research Achievements |
We have proposed Hsu-Anastasopoulos spatially coupled codes and MacKay-Neal codes. The proposed codes was proved to achieve the channel capacity of binary erasure channels with bounded degree distributions. We developed a fast encoding method of the proposed codes and rateless coding methods that achieve the capacity. We have developed non-binary codes and spatially coupled codes for quantum error correction. We have proved that the proposed codes universally achieve the symmetric information rate of the arbitrary generalized erasure channels.
