Network Information Theory is an extension\nof Shannon\u2019s Information Theory to Networks. \nWe have thought that the key to the successful development of new mobile\nwireless communications system concept should be to utilize the latest results\nof Network Information Theory in the most suitable forms, which satisfy network\nobjectives and requirements in efficient way. \nAlso, identifying the theoretical performance limit is of most crucial\nimportance. Under such significant and ambitious goals and objectives, he has\nworked for almost 40 years including experiences in the industry (NTT\/NTT\nDoCoMo), Center for Wireless Communications (University of Oulu, Finland), and\nJAIST. Recently, he has been intensively\nresearching how Lossy Distributed Multi-terminal Source Coding Theory, with the\naim of how the theoretical framework should be modified so that it can be\nbest-suited to mobile wireless cooperative communications systems having\nmassive wireless devices. He also has\nconsidered how Network Information Theory should be understood in the design of\nwireless mesh networks, relay communications, sensor networks, Internet-of-Things\n(IoT) and Vehicle-to-Things (V2X) networks. \nHis challenge has included theoretical limit analysis, algorithm design,\nand verification by simulations. <\/p>\n\n\n\n
The reason for the pursuance towards the\ngoals described above is that in IoT, V2X, and Edge computing, the lossless\nrecovery of information observed by the sensing devices should not necessarily\nbe End-to-End Lossless. In other words,\nthe purpose of IoT network is NOT the full recovery of observations, but to\nmake correct decisions based on the observations made by massive sensing\ndevices which are assumed to be distributed around the target, and hence the\ncorrected information is correlated. By\nutilizing the source correlation knowledge at the receiver, Ultra Reliable Low\nLatency Communication (URLLC) is possible, even though packet-wise transmission\nis lossy. <\/p>\n\n\n\n
In the Seminar, also the recent results of\nhis research group are introduced, which covers performance analysis of\nLossless\/Lossy Multi-source transmission over fading Multiple Access Channels,\nsuch as Wyner Ziv systems over fading MAC. \n<\/p>\n\n\n\n
At the final stage, his future view of the\nresearch trends, one of which, he thinks, is towards creation of the\ntheoretical framework for Distributed Hypothesis Testing, will be briefly\nintroduced. <\/p>\n\n\n\n

He joined Nippon\nTelegraph and Telephone Corporation (NTT), in 1980, where he was involved in a\nlot of research and development projects mobile wireless communications\nsystems. In 1992, he transferred to NTT DoCoMo, where he researched on\ncode-division multiple-access techniques for mobile communication systems. In\n1994, he transferred to NTT America, where he served as a Senior Technical\nAdvisor of a joint project between NTT and NEXTEL Communications. In 1996, he\nreturned to NTT DoCoMo, where he served as the Head of the Radio Signal\nProcessing Laboratory, until 2001. He researched on adaptive signal processing,\nmultiple-input multiple-output turbo signal detection, interference\ncancellation, and space-time coding techniques for broadband mobile\ncommunications. In 2002, he moved to the University of Oulu, Finland, where he served\nas a Professor at Centre for Wireless Communications. In 2006, he has served as\na Visiting Professor with the Ilmenau University of Technology, Ilmenau,\nGermany, supported by the German MERCATOR Visiting Professorship Program. Since 2007, he has been serving as a\nProfessor with the Japan Advanced Institute of Science and Technology (JAIST),\nJapan, while also keeping a cross-appointment position with the University of\nOulu. After his retirement from JAIST,\nhe moved to IMT-Atlantic, France, where he is serving as an invited\nprofessor. He is also Professor Emeritus\nof JAIST and University of Oulu. <\/p>\n\n\n\n
Prof. Matsumoto is a member of the IEICE.\nHe has led a lot of projects supported by the Academy of Finland, European FP7,\nand the Japan Society for the Promotion of Science and Japanese private\ncompanies. He has been appointed as a Finland Distinguished Professor, from\n2008 to 2012, supported by Finnish National Technology Agency (Tekes) and\nFinnish Academy, under which he preserves the rights to participate in and\napply for European and Finnish National Projects. He was a recipient of IEEE\nVTS Outstanding Service Award, in 2001, Nokia Foundation Visiting Fellow\nScholarship Award, in 2002, IEEE Japan Council Award for Distinguished Service\nto the Society, in 2006, the IEEE Vehicular Technology Society James R. Evans\nAvant Garde Award, in 2006, Thuringen State Research Award for Advanced Applied\nScience, in 2006, the 2007 Best Paper Award of the Institute of Electrical,\nCommunication, and Information Engineers of Japan, in 2008, Telecom System\nTechnology Award from the Telecommunications Advancement Foundation, in 2009,\nIEEE Communication Letters Exemplary Reviewer, in 2011, Nikkei Wireless Japan\nAward, in 2013, IEEE VTS Recognition for Outstanding Distinguished Lecturer, in\n2016, and IEEE TRANSACTIONSON COMMUNICATIONS Exemplary Reviewer, in 2018. He\nhas been serving as an IEEE Vehicular Technology Distinguished Speaker, since\n2016.<\/p>\n\n\n\n
