The research on white LED wireless communication technology in China started
relatively late. Representative units include the Institute of Semiconductors of the
Chinese Academy of Sciences, Fudan University, PLA Engineering University, Jinan
University, Xi’an Institute of Technology, Changchun University of Science and
Technology, Beijing University of Posts and Telecommunications, Zhejiang University, Southwest Jiaotong University, etc. [5–14]. In 2009, the Institute of Semiconductors, Chinese Academy of Sciences studied the application of VLC in home
control and broadband access, which was exhibited at the 2010 Shanghai world
expo. Figure 11.2 shows the device eye diagram by using a delta-doping LED light
source.
