专家介绍：Yongpeng  Wu received the B.S. degree in telecommunication engineering  from Wuhan University, Wuhan, China, in July 2007, the Ph.D. degree in communication and signal processing with the National Mobile Communications Research Laboratory, Southeast University, Nanjing, China, in November 2013. Dr. Wu is currently a research professor (tenure�track) with Shanghai Key Laboratory of Navigation and location based services, Shanghai Jiao Tong University, China. Previously, he was senior research fellow with Institute for Communications Engineering, Technical University of Munich, Germany and the Humboldt research fellow and the senior research fellow with Institute for Digital Communications, University Erlangen�Nurnberg, Germany. During his doctoral studies, he conducted cooperative research at the Department of Electrical Engineering, Missouri University of Science and Technology, USA. His research interests include massive MIMO/MIMO systems, physical layer security, signal processing for wireless communications, and multivariate statistical theory.

Dr. Wu was awarded the IEEE Student Travel Grants for IEEE International Conference on Communications (ICC) 2010, the Alexander von Humboldt Fellowship in 2014, the Travel Grants for IEEE Communication Theory Workshop 2016, and the Excellent Doctoral Thesis Awards of China Communications Society 2016. He was an Exemplary Reviewer of the IEEE Transactions on Communications in 2015, 2016. He is the lead guest editor for the upcoming special issue ``Physical Layer Security for 5G Wireless Networks" of the IEEE Journal on Selected Areas in Communications. He is currently an editor of the IEEE Access and IEEE Communications Letters. He has been a TPC member of various conferences, including Globecom, ICC, VTC, and PIMRC, etc.

报告内容：Massive MIMO is regarded as the most important technology for next generation communications and will be widely adopted in the future networks. Therefore, its ability to perform secure transmission in presence of eavesdroppers is crucial for the future network security. In this talk, I will first introduce the background of secure massive MIMO communication and discuss the main secrecy threat for massive MIMO technology.  Then, I will introduce several secure transmission designs and show their performance by some numerical results. Finally, I will explain the main bottlenecks of current designs and discuss the possible improvements in future research work
