Professor Dr.Hideo Kobayashi received the B.E., M.E and PHD in 1975, 1977 and 1989, respectively from Tohoku University in Japan. He joined KDD in 1977, and engaged in the research and development of digital fixed satellite and mobile satellite communication systems. From 1988 to 1990, he was with International Maritime Satellite Organization (INMARSAT) at its London Headquarters as the Technical Assignee and involved in the design and development of Inmarsat-M communications system which can provide the global mobile satellite communications services by using the portable terminals. From 1997 to 1998, he was with the NEC ICO project office as the technical consultant at its London office and involved in the development of the ICO personal satellite communications system which can allow the ordinary common users to access the Non-Geostationary Satellite Orbit (Non-GSO) directly from any wherein the world by using the handheld terminals. Since 1998 he has been the Professor of Graduate School of Engineering, Mie University in Japan. From 2007 to 2009, he was the Executive Vice President of Mie University in charge for the ICT and International affairs. From 2009 to 2012, he was the Executive Vice President of Mie University in charge for the ICT and International affairs. From 2009 to 2012, he was the Dean of Graduate School of Engineering of Mie University. He is currently the Member of the Education and Research Council of Mie University. His research interests include the advanced modulation and access techniques for the terrestrial and satellite mobile communications and wireless LAN communications. He published more than 200 papers in the refereed International conference and journal.
OFDM (Orthogonal Frequency Division Multiplexing) technique has been received a lot of attentions especially in the field of multimedia broadband wireless communications system because of its efficient usage of frequency bandwidth and robustness to multi-path fading. From these advantages, OFDM technique has been already adopted as the standard transmission techniques in the terrestrial digital broadcasting, wireless LAN and next generation of terrestrial mobile communications systems. Furthermore OFDM has been considered as one of the promising technique for the future wireless communication systems from that OFDM has potential capability to enhance its performance further by merging with multiple access method, forward error correction method, adaptive modulation and frequency channel assignment method and multi-input and multi-output (MIMO) method. However some challenging research topics still remain unsolved in the OFDM system, PAPR (peak to averaged power ratio) problem in the non-linear channel and Doppler frequency spread problem in the time-varying fading channel, all of which would lead the fatal degradation of OFDM performance. This presentation firstly introduces the history of OFDM technique and fundamental theory and then presents some solutions for the above challenging research topics.

His research interests are in Control, Modelling and Signal Processing with applications in the fields of satellite, bio-medical, applied mechanics and robotics. In recognition of his expertise, several research grants have been awarded to him by Ministry of Science and Technology and Ministry of Higher Education. He has published more than 70 papers in Journals and 200 papers in Conference Proceedings. He received his professional qualification as Charted Engineer from the Engineering Council, United Kingdom in 2005 and also a member to the Institute of Engineering and Technology, United Kingdom
Physical system is very complex in nature and basically will generate quantitative output data for any given inputs. The output, being natural or force response, can be generated by applying rule or law. However, to apply the rule and interpreting its performance we need to represent or analogize all the subsystems that made up the system. The system can be presented as mathematical function or model. The systems are, mainly, dynamic as such they are in differential equations form. Model that is derived from physical law is class as White-box. Naturally, these equations are non-linear and analyzing such relationship is very complex and the analyses to be qualitative solutions. This solution can be presented in time series relationship and is classed as Grey-box model. The upward trends of signal processing, due to an advent of computer power, tend to simplify analysis by focusing mainly on the input-output variables. This approach, dubbed as Black-box, is attractive as it is very flexible and speedier development time. The talk will present the various type of model with its respective examples based on human, robotics and satellite system.
