讲座人介绍
Xiang-Gen Xia received his B.S. degree in mathematics from Nanjing Normal University, Nanjing, China, and his M.S. degree in mathematics from Nankai University, Tianjin, China, and his Ph.D. degree in electrical engineering from the University of Southern California, Los Angeles, in 1983, 1986, and 1992, respectively. He is currently the Charles Black Evans Professor, Department of Electrical and Computer Engineering, University of Delaware, Newark, Delaware, USA.
Dr. Xia was the Kumar’s Chair Professor  Group Professor (guest)  in Wireless Communications, Tsinghua University, during 2009-2011, the Chang Jiang Chair Professor (visiting), Xidian University, during 2010-2012, and the WCU Chair Professor (visiting), Chonbuk National University, during 2009-2013. Dr. Xia’s current research interests include space-time coding, MIMO and OFDM systems, digital signal processing, and SAR and ISAR imaging. He is the author of the book Modulated Coding for Intersymbol Interference Channels (New York, Marcel Dekker, 2000).
Dr. Xia received the National Science Foundation (NSF) Faculty Early Career Development (CAREER) Program Award in 1997, the Office of Naval Research (ONR) Young Investigator Award in 1998, and the Outstanding Overseas Young Investigator Award from the National Nature Science Foundation of China in 2001. He is currently serving and has served as an Associate Editor for numerous international journals including IEEE Transactions on Signal Processing,  IEEE Transactions on Wireless Communications,  IEEE Transactions on Mobile Computing,  IEEE Transactions on Vehicular Technology, and Science China -- Information Sciences.  Dr. Xia is Technical Program Chair of the Signal Processing Symp., Globecom 2007 in Washington D.C. and the General Co-Chair of ICASSP 2005 in Philadelphia. He is a Fellow of IEEE.

讲座内容
In this talk, I will briefly discuss the importance of mathematics in electrical engineering. From my experience in USA over the past decades, I see that the most significant change in human daily life is in communications, such as smart phones, where mathematics plays an important role. I will briefly introduce some of the key components of math in communications: some elementary math and some more advanced math, such as, finite fields and orthogonal designs (or compositions of quadratic forms) etc. I will finally briefly show some of our recent results on orthogonal designs.
