Luca Sanguinetti
Biography: Luca Sanguinetti received the Laurea Telecommunications Engineer degree (cum laude) and the Ph.D. degree in information engineering from the University of Pisa, Italy, in 2002 and 2005, respectively. Since 2005 he has been with the Dipartimento di Ingegneria dell’Informazione of the University of Pisa. In 2004, he was a visiting Ph.D. student at the German Aerospace Center (DLR), Oberpfaffenhofen, Germany. During the period June 2007 - June 2008, he was a postdoctoral associate in the Dept. Electrical Engineering at Princeton. During the period June 2010 - Sept. 2010, he was selected for a research assistantship at the Technische Universitat Munchen. From July 2013 to July 2015 he was with the Alcatel-Lucent Chair on Flexible Radio, Supelec, Gif-sur-Yvette, France. Dr. Sanguinetti is currently serving as an Associate Editor for the IEEE SIGNAL PROCESSING LETTERS. He served as an Associate Editor for IEEE TRANSACTIONS ON WIRELESS COMMUNICATIONS, and IEEE JOURNAL ON SELECTED AREAS OF COMMUNICATIONS (series on Green Communications and Networking) and as Lead Guest Editor of IEEE JOURNAL ON SELECTED AREAS OF COMMUNICATIONS 2016 Special Issue on ”Game Theory for Networks”. Dr. Sanguinetti served as Exhibit Chair of the 2014 IEEE International Conference on Acoustics, Speech, and Signal Processing (ICASSP) and as the general co-chair of the 2016 Tyrrhenian Workshop on 5G&Beyond. His expertise and general interests span the areas of communications, with special emphasis on multi-antenna communications, Massive MIMO, energy-efficient communications, and network design. He was the co-recipient of two best paper awards: IEEE Wireless Commun. and Networking Conference (WCNC) 2013 and IEEE Wireless Commun. and Networking Conference (WCNC) 2014. He is also the recipient of the FP7 Marie Curie IEF 2013 “Dense deployments for green cellular networks”. Dr. Sanguinetti is an Senior IEEE Member.
Talk title: A fresh look at massive MIMO.
Abstract: Since its inception, the following facts about Massive MIMO had been taken for granted without further questioning: 1) Due to pilot contamination, the capacity saturates as the number of antennas increases indefinitely; 2) Maximum ratio precoding/combining are asymptotically optimal; 3) Sophisticated linear combining and precoding schemes can only improve the performance for finite number of antennas. The aim of this talk is to show that all of these “facts” are incorrect and essentially an artifact from using simplistic channel models and suboptimal precoding/combining schemes. Specifically, we show that with multicell MMSE precoding/combining and a tiny amount of spatial channel correlation or large-scale fading variations over the array, the capacity increases without bound as the number of antennas increases, even under pilot contamination.
Asimakis Kokkos
Biography: Asimakis Kokkos serves as the MulteFire Alliance Technical Specification Working Group Chair driving the creation of timely and competitive standards to give MulteFire the necessary technological edge to deliver its objectives. Makis is also heading Industry Engagement Strategic Initiatives Steering at Nokia Mobile Networks, bringing together modern concepts of standardization and innovation. Makis joined Nokia in 1994,and held leadership positions spanning from global services to research and standardization. He has been a pioneer in getting frequency bands opened in Europe for new license exempt systems and mesh networks, led technology and standardization work in China, and has served as the chairman of Information and Communication Technology in EU China Chamber of Commerce. Makis received his first degree in Physics and Electronic Automation from University of Athens, Greece, his MSc degree in Digital Communication Systems from Loughborough University, UK and his PhD in modulation and coding from Bangor University, UK. He is a UK Chartered Engineer and Fellow of the Institution of Engineering and Technology.

Talk title: The role of MIMO in next generation mobile communications. [Download]
Abstract: The next generation mobile systems will be very demanding in capacity and performance and will be planned not only for sub 6GHz bands but also for higher frequencies (mm Wave). Beamforming can increase capacity and performance in mobile networks and will play a key role in the design of the next generation mobile systems. Active antennas will enable beamforming and MIMO and they are becoming technically and commercially feasible. Beamforming and MIMO are currently standardized in 3GPP.

Talk title: Orbital Angular Momenta (OAM) Multiplexing: from basic principles to realistic demos.
Abstract: Orbital Angular Momenta (OAM) multiplexing has drawn great attention over the past years as a method of multiplexing data streams in line-of-sight situations. This talk will give an overview of the technology, starting with the basic principles, discussing the relationship to spatial multiplexing, and analyzing practical constraints as well as impacts of realistic propagation effects.
