[Abstract]:This thesis comes from the project of Science and Technology support Program of Jiangsu Province, "Technology Research and system Development of WLAN based on visible Light" (No.: BEBE2011177). The main work is to design and implement the high-speed transmission link based on visible light communication. Based on the analysis of the design requirements, this paper proposes an overall scheme of high-speed transmission link based on visible light communication. The hardware circuit of visible light communication including transmitter and receiver is designed and implemented. The development platform of digital baseband processing is built and the corresponding software is developed. The developed visible light communication link is stable and reliable to meet the design requirements. The full text is divided into six chapters, including the following content: the first chapter is an introduction, introduced the research background and significance of the subject. The main content and the arrangement of each chapter are explained. The second chapter is the overall scheme design, and analyzes the application scene of WiFi access system based on visible light communication link. This paper discusses the key devices and techniques of limiting the rate of visible light communication, and designs the overall implementation scheme of the analog and digital parts of the visible light link. The third chapter is the design and implementation of the analog part. The overall implementation scheme of analog part is put forward, the hardware platform of analog part is built, the driving circuit and analog equalization circuit of transmitter and receiver are designed and realized. Chapter 4th is the design and implementation of digital part. The overall implementation scheme of digital part is put forward, and the hardware platform of digital part is built. Design and implement the data sending module and data receiving module using digital pre-equalization technology. Chapter 5th is performance testing and system tuning. The performance of the developed visible light communication link is tested by error rate test and unidirectional file transmission. The visible light communication link is applied to the WiFi access system for system tuning. The performance test and the system tuning result show that the developed visible light communication link is stable and reliable. Chapter 6th is a summary and prospect of the full text work, and put forward the idea of future work.
