Next-Generation GNSS Signal Design

Dr. Zheng Yao received his B.E. degree in electronics information engineering and his Ph.D. degrees in information and communication engineering from Tsinghua University, Beijing, China, in 2005 and 2010, respectively, where he is currently an Associate Professor with the Department of Electronic Engineering. He is the main inventor of asymmetric constant envelope binary offset carrier and quadrature multiplexed binary offset carrier modulations, which are employed in the BeiDou Navigation Satellite System (BDS) B2 and B1 civil signals, respectively. His primary areas of interest include the next-generation satellite navigation signals design, software-defined GNSS receiver, wireless localization technologies, and personal and vehicular positioning in challenging environments. Dr. Yao is a Senior Member of Institute of Electrical and Electronic Engineers (IEEE) and Institute of Navigation (ION). He has also been a Technical Program Chair and a Section Chair of several international conferences. He is the recipient of the 2017 ION Early Achievement Award, in recognition to his pioneering contributions in developing new GNSS signals and multiplexing techniques; and advancing the Chinese BDS signal design. He also received the 2008 Student Paper Award from the U.S. Institute of Navigation and the 2010 and 2013 Best Paper Awards from the China Satellite Navigation Conference. Dr. Mingquan Lu received the M.E. and Ph.D. degrees in electrical engineering from the University of Electronic Science and Technology of China, Chengdu. He is a professor with the Department of Electronic Engineering, Tsinghua University, Beijing, China. He directs the Positioning, Navigation, and Timing (PNT) Research Center, which develops global navigation satellite system (GNSS) and other PNT technologies. His current research interests include GNSS modeling and simulation, signal design and processing, and receiver development.
