Title: Semantic Communications: Principles and Challenges
Date: 20 June 2022
Time: 9:00 AM Eastern (New York time)
Duration: Approximately 1 Hour
Presenters: Dr. Zhijin Qin
Based on the IEEE Xplore® article: Deep Learning Enabled Semantic Communication Systems
Published: IEEE Transactions on Signal Processing, 2021 available in IEEE Xplore®
In past decades, conventional communication primarily focused on how to accurately and effectively transmit symbols, which is categorized as the first level of communications by Shannon and Weaver. With the developments of cellular communication systems, the achieved transmission rate is gradually approaching to the Shannon limit. Inspired by the power of deep learning, the semantic communication has been regarded as a promising solution to further improve the system efficiency, which is categorized as the second level of communications. Semantic communications aim to realize the successful semantic information exchange rather than receive the transmitted bit sequences or symbols accurately. In this talk, I will introduce the basis of semantic communications first. Our recent work on deep learning has enabled semantic communications will be presented. Research challenges are discussed at the end of the talk.
Zhijin Qin (M’16–SM'21) received the B.S. degree from the Beijing University of Posts and Telecommunications, Beijing, China, in 2012 and the Ph.D. degree on electronic engineering from the Queen Mary University of London (QMUL), London, U.K., in 2016. Since 2018, she has been a Lecturer with QMUL.
Her research interests include semantic communications, federated learning for wireless resource allocation, and compressive sensing.
Dr. Qin was the recipient of the 2017 IEEE GLOBECOM Best Paper Award, the 2018 IEEE Signal Processing Society Young Author Best Paper Award and the 2021 IEEE SPCC Early Achievement Award. She is an Associate Editor for the IEEE Transactions on Communications, IEEE Communications Letters, and IEEE Transactions on Cognitive Communications and Networking.
