Lossy Communication for IoT: from the multi-terminal source coding viewpoint

by Professor Tad Matsumoto


Time: 14:00-16:00

Venue: TS 127


Abstract of the Seminar:

A goal of this talk is to provide audience with the knowledge about the relationship between lossy-multiple source coding with a helper and Internet-of-Things (IoT).  This talk is started by introductory presentation, but non mathematical, between them.  Then, we introduce Intelligent IoT system concept, where recursive structure is introduced to connect the processing between sensors and the fusion center where an action/decision is followed by the statistical analysis.  The recursive structure makes it possible to track the mobility of the sensing target.  Hence, this concept can effectively utilized in collision avoidance system, for example. 

Then, after the brief explanations of the system concept, we introduce our footprint and historical background of our research work.  We introduce how the conventional decode-and-forward relaying system is further modified to lossy forwarding, which we found is largely related to multi-terminal coding theory with a helper.   A latest result of the multiple terminal source coding technique with a helper in a lossy case is also introduced with a high level mathematical way.

This talk covers both non-mathematical to very highly mathematical parts.  The presenter, highly appreciate that the audience remain listening to the talk and trying to understand how they are connected by participating in the entire portion of the talk. 



Tad Matsumoto received his B.S., M.S., degrees, both under the mentorship by Prof. Shin-Ichi Takahashi, and Ph.D. degree under the supervision by Prof. Masao Nakagawa,  from Keio University, Yokohama, Japan, in 1978, 1980, and 1991, respectively, all in electrical engineering. He joined Nippon Telegraph and Telephone Corporation (NTT) in April 1980. Since he engaged in NTT, he was involved in a lot of research and development projects, all for mobile wireless communications systems. In July 1992, he transferred to NTT DoCoMo, where he researched Code-Division Multiple-Access techniques for Mobile Communication Systems.  In April 1994, he transferred to NTT America, where he served as a Senior Technical Advisor of a joint project between NTT and NEXTEL Communications. In March 1996, he returned to NTT DoCoMo, where he served as a Head of the Radio Signal Processing Laboratory until August of 2001; He worked on adaptive signal processing, multiple-input multiple-output turbo signal detection, interference cancellation, and space-time coding techniques for broadband mobile communications. In March 2002, he moved to University of Oulu, Finland, where he served as a Professor at Centre for Wireless Communications.  In 2006, he served as a Visiting Professor at Ilmenau University of Technology, Ilmenau, Germany, funded by the German MERCATOR Visiting Professorship Program.  Since April 2007, he has been serving as a Professor at Japan Advanced Institute of Science and Technology (JAIST), Japan, while also keeping a cross-appointment position at University of Oulu.

He has led a lot of projects funded by Academy-of-Finland, European FP7, and Japan Society for the Promotion of Science as well as by Japanese private companies. 

Prof. Matsumoto has been appointed as a Finland Distinguished Professor for a period from January 2008 to December 2012, funded by the Finnish National Technology Agency (Tekes) and Finnish Academy, under which he preserves the rights to participate in and apply to European and Finnish national projects. Prof. Matsumoto is a recipient of IEEE VTS Outstanding Service Award (2001), Nokia Foundation Visiting Fellow Scholarship Award (2002), IEEE Japan Council Award for Distinguished Service to the Society (2006), IEEE Vehicular Technology Society James R. Evans Avant Garde Award (2006), and Thuringen State Research Award for Advanced Applied Science (2006), 2007 Best Paper Award of Institute of Electrical, Communication, and Information Engineers of Japan (2008), Telecom System Technology Award by the Telecommunications Advancement Foundation (2009), IEEE Communication Letters Exemplifying Reviewer Award (2011), Nikkei Wireless Japan Award (2013), and 2016 IEEE VTS Recognition for Outstanding Distinguished Lecturer.  He is a Fellow of IEEE and a Member of IEICE.  He is serving as an IEEE Vehicular Technology Distinguished Lecture since July 2011.
