Abstract

High-mobility broadband communication channels tend to suffer from fast time-varying multipath fading with large Doppler spread, also known as doubly selective fading. Doubly selective fading becomes more severe when future communications move to higher frequency bands in the mm-wave or sub-THz range. Multipath fading introduces inter-symbol interference (ISI) in single-carrier communication systems, Doppler spread introduces inter-carrier interference (ICI) to multi-carrier communication. Tracking the fast-varying fading channel states also requires more pilot overhead, which cuts communication efficiency. On the other hand, multipath presents frequency diversity, while Doppler effects present time diversity, which are good against signal deep fades. In this talk, I will share recent results in constructing doppler-resilient multipath receivers with low pilot overhead, by exploiting BEM channel modelling, pseudo-pilot, iterative channel estimation and equalization, and other techniques, turning the foes in doubly selective fading channel to diversity benefits.

Biography

Professor Yong Liang GUAN is an Associate Vice President of the Nanyang Technological University (NTU), Singapore, and a Professor of Communication Engineering at the School of Electrical and Electronic Engineering in NTU. He is also the founder and director of the Continental-NTU Corporate Research Lab. He obtained PhD degree in Electrical and Electronic Engineering (EEE) from the Imperial College London, UK, and Bachelor of Engineering with First Class Honours in EEE from the National University of Singapore. His research interests broadly include coding and signal processing for communication systems and data storage systems. He has published more than 450 journal and conference papers, an invited monograph, and 2 books. He was an editor of the Singapore V2X standard IMDA TS DSRC Issue 1 Rev 1, October 2017published by the Infocomm and Media Development Authority (IMDA) of Singapore. He is also an Editor for the IEEE Transactions on Vehicular Technology, and a Distinguished Lecturer of the IEEE Vehicular Technology Society. He has secured over S$70 million of external research funding. He established the Continental-NTU Corporate Lab, Phase-1 Schaeffler Hub for Advance Research, and NTU-NXP V2X Testbed in NTU. He has 40 filed patents and 7 granted patents (some of which were licensed to NXP Semiconductors, Continental Automotive).
