Abstract:Massive machine type and low-latency communications are already indispensable use cases of fifth Generation (5G) networks. Low-latency in the order of less than1msrepresents one of the cornerstone prerequisites of the latter cases with applications ranging from remote surgery to virtual reality. Unlike conventional communication realized with largePackets approaching Shannon’s infinite blocklength assumption, the 5G low-latency applications can only be realized in the finite blocklength regime (few hundreds of channel uses, e.g.,100-300for vehicle-to-vehicle communication). Motivated by the lack of analytical investigation on the impact of practical channel state information (CSI) estimation schemes on the performance of finite blocklength communication, finite blocklength transmission under imperfect CSI will be presented. In this talk, we will highlight the impact of non-ideal CSI on point-to-point wireless data link transmisions and distributed multiple-input multiple outpur (MIMO) communication systems. Finaly, some new simple approximations in closed form for key system performance metrics such as the outage probability, error probability, mean transmission delay, total system goodput, and level crossing rate, (LCR)will be presented and discussed.

He received the B.Sc. degree in physics from the Aristotle University of Thessaloniki, Greece, in 1993, the M.Sc. degree in digital systems engineering from the Heriot-Watt University, Edinburgh, U.K., in 1995, the M.Sc. degree in decision sciences from the Athens University of Economics and Business, in 2000, and the Ph.D. degree in electrical engineering from the University of Patras, Greece, in 2006. He is currently a Professor in the School of Intelligent Systems Science & Engineering at Jinan University, Zhuhai Campus, Zhuhai, China. He is also Honorary Professor at Shandong Jiaotong University, Jinan, China. His research interests include the broad areas of cognitive radio, communication theory, wireless powered communication systems, optical wireless communication, and ultra-reliable low-latency communication. Prof. Tsiftsis has been appointed to a 2-year term as an IEEE Vehicular Technology Society Distinguished Lecturer (IEEE VTS DL), Class 2018. Dr. Tsiftsis acts as a Reviewer for several international journals and conferences. He has served as Senior or Associate Editor in the Editorial Boards of IEEE Transactions on Vehicular Technology, IEEE Communications Letters, IET Communications, and IEICE Transactions on Communications. He is currently an Area Editor for Wireless Communications II of the IEEE Transactions on Communications and an Associate Editor of the IEEE Transactions on Mobile Computing.
