Compressed Spectrum Sensing and Learning: From Theory to Practice
This presentation discusses various aspects of Compressed Spectrum Sensing (CSS) systems to address existing challenges and enhance practical implementation. The research contributes to some of the key techniques that enhance the performance of CSS systems in a practical framework, including refining spectrum recovery accuracy, optimising sampling pattern design, and improving reconstruction and machine learning algorithms. This talk will also present a software-defined system for CSS on mmWave which achieves real-time spectrum sensing for a 3.072 GHz bandwidth signal at a 28.5 GHz centre frequency, utilising Bayesian sparsity estimation and data decimation algorithms for robust performance.
Yue Gao is a Chair Professor at School of Computer Science, and Director of Intelligent Networking and Computing Research Centre at Fudan University, China and a Visiting Professor at University of Surrey, UK. He received the Ph.D. degree from the Queen Mary University of London (QMUL) U.K., in 2007. He has then worked as a Lecturer, Senior Lecturer, Reader and Chair Professor at QMUL and University of Surrey, respectively. His research interests include smart antennas, sparse signal processing and cognitive networks for mobile and satellite systems. He has published over 200 peer-reviewed journal and conference papers and over 7000 citations. He was a co-recipient of the EU Horizon Prize Award on Collaborative Spectrum Sharing in 2016 and elected as an Engineering and Physical Sciences Research Council Fellow in 2017. He is a member of the Board of Governors and Distinguished Lecturer of the IEEE Vehicular Technology Society (VTS), Chair of the IEEE ComSoc Wireless Communication Technical Committee, past Chair of the IEEE ComSoc Technical Committee on Cognitive Networks. He has been an Editor of several IEEE Transactions and Journals, and Symposia Chair, Track Chair, and other roles in the organising committee of several IEEE ComSoC, VTS and other conferences.
