5G Wireless

Friday, 27 April, 2018 - 16:00
Aula van de Tweede Hoofdwet
Thermotechnisch Instituut Kasteelpark Arenberg
Lecture Francqui Chair

Speaker: Prof. Robert Calderbank, Duke University

Abstract: The world of wireless communications is changed rapidly, and I will look back at GSM, CDMA, and OFDM, and describe how these technologies were developed in response to demanding use cases. I will then try to look forward at use cases motivating 5G wireless, such as drones, high speed trains and the Internet of Things (IoT). I will explore what might be possible with OFDM, and what might be more difficult. The discussion will motivate the introduction of OTFS (Orthogonal Time Frequency Space), a physical layer technology that can be architected as an OFDM overlay. I will explain potential advantages of OTFS over legacy multicarrier modulation schemes (OFDM) in the context of various 5G use cases such as MU-MIMO equalization and precoding, communication under high Doppler conditions (V2X and V2V) and communication under power constraints (such as in IoT).
