Abstract:
Future wireless communication requires high data rate and massive connection for emerging applications such as Internet of things (IoT). In particular, in human-computer interaction scenarios, humans may simultaneously control multiple IoT devices using speech command, thus making audio communication pervasive in a small-range wireless network. However, a spectrum resource-constrained network may not be able to support the broad and prolonged wireless audio communication. This, in turn, motivates the development of semantic communication technique that allows devices to only transmit small amounts of semantic information. Semantic communication aims at minimizing the difference between the meanings of the transmitted messages and that of the recovered messages, rather than the recovered symbols. Using semantic communication technique, one can reduce the communication overheads. In this talk, I will talk about the research about goal-oriented semantic communication, including audio semantic communication, semantic communication with distributed implementation, and a compute-then-transmit framework for semantic communication.
Bio:
Zhaohui Yang received the Ph.D. degree in communication and information system with the National Mobile Communications Research Laboratory, Southeast University, Nanjing, China, in May 2018. From May 2018 to October 2020, he was a postdoctoral research associate with the Center for Telecommunications Research, Department of Informatics, King's College London, UK. He is currently a visiting scholar with College of Information Science and Electronic Engineering Zhejiang Key Lab of Information Processing Communication and Networking, Zhejiang University, and also a research fellow with the Department of Electronic and Electrical Engineering, University College London, UK. He is an Associate Editor for the IEEE Communications Letters, IET Communications and EURASIP Journal on Wireless Communications and Networking. He has guest edited a feature topic of IEEE Communications Magazine on Communication Technologies for Efficient Edge Learning and a special issue of Journal on Selected Areas in Communications for Beyond Transmitting Bits: Context, Semantics and Task-Oriented Communications. He was a Co-Chair for workshops on edge learning and wireless communications in several conferences including the IEEE International Conference on Communications (ICC), the IEEE Global Telecommunication Conference (GLOBECOM), the IEEE Wireless Communications and Networking Conference (WCNC), and the IEEE International Symposium on Personal, Indoor and Mobile Radio Communication (PIMRC). His research interests include semantic communication, federated learning, reconfigurable intelligent surface, and NOMA. He was a TPC member of IEEE ICC during 2015-2021 and GLOBECOM during 2017-2021. He was an exemplary reviewer for IEEE Transactions on Communications in 2019 and 2020.
