报告题目：Practical Visible Light Communication System Leveraging LED Sensing
报告人：Dr. Yanbing Yang (Nanyang Technological University, Singapore)
Known as a “green” technology, Visible Light Communication (VLC) piggybacking on existing lighting system has been considered as a promising access technique for next-generation wireless systems (5G). However, whereas major research efforts in the field of VLC are pursuing higher data rate, exploring the potential of VLC employing Commercial Off-The-Shelf (COTS) devices and providing seamless connectivity for mobile users seem to be ignored. To this end, my research focuses on developing a practical VLC system which can offer roaming support for users with commonly handy devices, e.g. smartphones. In order to have a proper feedback channel for roaming support, we innovate in converting part of the LED luminaires (already used as the VLC transmitters) into light sensors. By sensing the disturbance to the ambient diffuse reflection caused by user presence and mobility, our system is able to adaptively handoff its transmissions from one luminaire to another, so as to keep up with user mobility and hence to offer an adequate roaming support. In this talk, I will introduce my research on both VLC and LED sensing as well as how to integrate VLC with LED sensing to improve the performance of VLC for mobile users.
Dr.Yanbing Yang received his BS degree in Industrial Engineering from University of Electronic Science and Technology of China, China, in 2010, and the MS degree in Electronic and Communication Engineering from University of Electronic Science and Technology of China, China, in 2013.
