| Research Abstract |
Through revisiting the framework of statistical-mechanical nformatics for analyzing problems in the fields of information and communication in terms f information theory and statistical estimation theory, we have aimed at reformulating the ramework of statistical-mechanical informatics, as well as consolidating its efficiency, as a oolbox applicable to more realistic problem settings. In particular, in situations where ne cannot assume perfect knowledge about channel states, which are of principal concern n the context of wireless communication, we have shown that the analytical framework of tatistical-mechanical informatics is successfully applied to such situations to yield useful indings in view of designing wireless communication systems, demonstrating its efficiency.
