| Outline of Final Research Achievements |
Practical lattice codes to improve the spectral efficiency of wireless communications were developed. In addition, for both wireless and data storage systems, efficient quantization methods to reduce device power consumption were also developed. Collaborative research at four overseas universities was performed. Concretely, the following results were obtained: (1) A practical decoding algorithm for LDPC code-based lattices, (2) A lattice shaping technique that can achieve 81% of the possible shaping gain (3) Optimal quantization for continuous-output channels. (4) Lattice-based schemes achieve full diversity of the wireless MARC channel. Also, coding schemes for DNA storage systems were considered. Presentations were given at respective universities to disseminate the results of the Kiban-B project.
