Research Area
Laboratory
I started my academic life in the theory of algebraic error-correcting codes and its applications, and have recently been interested also in information theory. For the past 15 years I have been studying on the asymptotic capability of algebraic error-correcting codes, which are able to prove Shannon's fundamental theorem for noisy channel not by random coding technique but by constructive coding. Now I would like to study on Shannon's channel coding theorem from the viewpoints of both the reliability function in information theory and the asymptotic distance ratio in coding theory. As the final purpose (dream) in my academic life, I will try to challenge the fundamental problems to determine the reliability function for low rates and to clarify relationship between the reliability function and the asymptotic distance ratio
