5G on stage: this technology will change your life (and you don’t know it yet)

Arturo Azcorra, Director, IMDEA Networks Institute; Professor, Universidad Carlos III de Madrid, Spain
University Carlos III of Madrid (UC3M) participates in the seventeenth edition of the Madrid Science Week with more than thirty activities (all free-of-charge ) that will offer a first-hand knowledge of the Institution's R&D program. IMDEA Networks is collaborating with UC3M in the staging of a multimedia, theatrical and informative show that explores the effects of 5G technology in our everyday lives. The show will held on November 7th in the Auditorium of the UC3M.

Two Approaches for the Performance Evaluation of Queueing Systems: Pricing and Scaling

Josu Doncel Vicente, Assistant Professor, Department of Applied Mathematics and Statistics, Faculty of Science and Technology, University of the Basque Country (UPV/EHU), Spain
Queueing theory, the set of probabilistic techniques that study waiting lines or queues, is a fundamental tool to analyze the performance of modern telecommunication networks. In this talk, we present the results of the performance analysis of two queueing systems.

OTFS: A New Generation of Modulation Addressing the Challenges of 5G

Christian Ibars Casas, Principal Engineer, Cohere Technologies, Santa Clara, CA, USA
A new two-dimensional modulation technique called Orthogonal Time Frequency Space (OTFS) modulation designed in the delay-Doppler domain is introduced as a waveform ideally suited to new 5G use cases. Through this design, which exploits full diversity over time and frequency, OTFS coupled with equalization converts the fading, time-varying wireless channel experienced by modulated signals such as OFDM into a time-independent channel with a complex channel gain that is roughly constant for all symbols. Thus, transmitter adaptation is not needed. This extraction of the full channel diversity allows OTFS to greatly simplify system operation and significantly improves performance, particularly in systems with high Doppler, short packets, and large antenna arrays. Simulation results indicate at least several dB of block error rate performance improvement for OTFS over OFDM in all of these settings which translates to significant spectral efficiency improvements.

SoftAir: A Software-Defined Networking Architecture for 5G Wireless Systems

Prof. Ian F. Akyildiz, Broadband Wireless Networking Lab, School of Electrical and Computer Engineering Georgia Institute of Technology, Atlanta, GA, USA
SoftAir is a new wireless software-defined architecture with network function virtualization (NFV) solutions for 5G wireless systems. The concept of SDN has been proposed to efficiently create centralized network abstraction with the provisioning of programmability over the entire network.
