Since he joined NTT Corporation, he has been engaged in the research and development of multimedia data transmission technologies, especially in the area of channel coding techniques. He studied a novel channel coding scheme called FireFort-LDGM (Low Density Generator Matrix) code that includes a range of new algorithms to improve both the robustness and functionality of conventional LDGM codes. He solved a weakness in LDGM codes by using his sub-packet division method and layer-aware construction method, while retaining the advantages of LDGM codes such as high-bandwidth data transmission performance and low computational complexity. These proposed methods are so effective that FireFort-LDGM code is able to support a large set of code lengths and rates, which can be used in a wide range of applications over IP networks.
Moreover, he proposed the inclusion of FireFort-LDGM code in the next generation transport standard called MPEG media transport (MMT), specified by the Moving Picture Experts Group. Through his energetic activities to provide greater robustness by replacing the existing and widely used Pro-MPEG FEC code, FireFort-LDGM code has been accepted as one of the MMT-FEC codes. He has also contributed to other areas of MMT standard development, in particular to the FEC framework. In the near future, the MMT standard will be widely used in a number of new services including 4K/8K hybrid broadcast broadband TV and next generation super high realistic public viewing, such as concerts or sports events broadcast in real time.
As described above, for his groundbreaking contributions to technologies in the channel coding domain and MMT/MMT-FEC standardizations, he richly deserves the Yasuharu Suematsu Award.
