Mobile Ad Hoc Networks for Wide-Area Deployment
Niigata University, Niigata, Japan
An overview of the evolution of intelligent transport system supported by advances in information and communication technologies is presented. A concept and conditions of wide-area ad hoc network (WANET) are presented. Routing protocols for mobile ad hoc networks are reviewed with regard to WANET. Various node networking including fixed node networking, balloon node networking, automobile node networking, and unmanned aircraft (UA) node networking are described. With regard to fixed node networking and balloon node networking, implementation examples and operation experiences are discussed. With regard to automobile node networking, routing protocols are discussed based on a survey of geographic routing protocols for vehicular ad hoc networks. With regard to UA node networking, a system for surveillance of a wide disaster-affected area from the air supported by electric vehicle is considered. Finally a perspective on the evolution of WANET is presented.

Distributed MIMO Cooperative Signal Transmission for 5G
Research Organization of Electrical Communication, Tohoku University, Japan
After 35 years from its birth in 1979, mobile wireless communications networks have evolved into the 4th generation (4G). The mobile data traffic volume is growing explosively and therefore, significantly advanced spectrum- and energy-efficient wireless communication technology needs to be developed for the 5th generation (5G) mobile wireless communications networks. One promising approach is to adopt a distributed antenna small-cell network, in which a number of distributed antennas are deployed over a macro-cell area. Distributed antennas surrounding a user and user antennas form distributed MIMO channel. In this presentation, two types of distributed MIMO cooperative signal transmission technique are presented. One is space-time block coded (STBC) diversity, which aims to improve the macro-cell edge users’ throughput. The other is multi-user joint transmit/receive filtering, which aims to improve the sum-throughput of users in a good channel condition. When using cooperative signal transmission, peak-to-average power ratio (PAPR) of the transmit signal is increased. Therefore, PAPR reduction will be still necessary for battery-operated user terminal transmit power amplifiers. Blind selected mapping (blind SLM) which can effectively suppress the PAPR and requires no side information sharing is presented.
Fumiyuki Adachi received the B.S. and Dr. Eng. degrees in electrical engineering from Tohoku University, Sendai, Japan, in 1973 and 1984, respectively. In April 1973, he joined the Electrical Communications Laboratories of Nippon Telegraph & Telephone Corporation (now NTT) and conducted various researches on digital cellular mobile communications. From July 1992 to December 1999, he was with NTT Mobile Communications Network, Inc. (now NTT DoCoMo, Inc.), where he led a research group on Wideband CDMA for 3G systems. Since January 2000, he has been with Tohoku University, Sendai, Japan. His research interest is in the area of wireless signal processing (multi-access, equalization, antenna diversity, adaptive transmission, channel coding, etc.) and networking.
He is an IEICE Fellow and an IEEE Fellow. He was a recipient of the IEEE Vehicular Technology Society Avant Garde Award 2000, IEICE Achievement Award 2002, Thomson Scientific Research Front Award 2004, Ericsson Telecommunications Award 2008, Telecom System Technology Award 2009, Prime Minister Invention Award 2010, British Royal Academy of Engineering Distinguished Visiting Fellowship 2011, KDDI Foundation Excellent Research Award 2012, VTS Conference Chair Award 2014, C&C Prize 2014, and Rintaro Shida Award 2016.
