New Directions in Wireless Communications Systems: From Mobile to 5G

Beyond 2020, wireless communication systems will have to support more than 1,000 times the traffic volume of today's systems. This extremely high traffic load is a major issue faced by 5G designers and researchers. This challenge will be met by a combination of parallel techniques that will use more spectrum more flexibly, realize higher spectral efficiency, and densify cells. Novel techniques and paradigms must be developed to meet these goals. The book addresses diverse key-point issues of next-generation wireless communications systems and identifies promising solutions. The book's core is concentrated to techniques and methods belonging to what is generally called radio access network.

From 1993 to 1994 he was with National Documentation Center of National Research Institute. In 1995 he joined SPACETEC Ltd. as Technical Project Manager for VISA/EMEA VSAT Project in Greece. In 1996 he joined the Mobile Radio-Communications Laboratory as a research associate. From 1999 to 2002 he was with the Institute of Communication & Computer Systems responsible for the technical management of various research projects. In 2000 he became a member of the Board of Directors of OTESAT S.A. In 2002 he joined the University of Piraeus as an Assistant Professor. From 2007 to 2009 he served as Greek Delegate to the Mirror Group of the Integral Satcom Initiative. He has published more than 130 papers in International Journals and International Conference Proceedings. His current research interests include the development of new digital techniques for wireless and satellite communications systems, channel characterization, simulation, and modeling for mobile, mobile satellite, and future wireless communication systems, antenna selection and RF preprocessing techniques, new transmission schemes for MIMO systems, V2V communications, and energy efficient techniques for Wireless Sensor Networks. He has been a Senior Member of IEEE since 2002. In 1999 he was elected Chairman of the Communications Society of the Greek Section of IEEE.
