中文摘要：

为了保证马厩，室内的可见轻通讯(VLC ) 的正确、即时的高速度的传播，关键调整和解调，直角的频率部门 multiplexing (OFDM ) 的技术在这份报纸被学习。时间域同步，频率同步和接收装置的隧道均等被利用短、长的训练序言分析并且优化。而且，领域可编程的门数组(FPGA ) 开发董事会(Xilinx Kintex-7 ) 和 Verilog 硬件描述语言被用来认识到建议 OFDM-VLC 的设计系统。模拟和实验两个都验证这个系统的硬件图案的可行性。建议基于 OFDM 的 VLC 系统罐头进程信号在即时，它能在实际 VLC 应用程序系统被使用。

英文摘要：

In order to ensure stable,correct and real-time high-speed transmission of indoor visible light communication（VLC）,the key modulation and demodulation technologies of orthogonal frequency division multiplexing（OFDM） are studied in this paper. The time-domain synchronization,frequency synchronization and channel equalization of receiver are analyzed and optimized by utilizing short and long training preamble. Moreover,field programmable gate array（FPGA） development board（Xilinx Kintex-7） and Verilog hardware description language are used to realize the design of proposed OFDM-VLC system. Simulation and experiment both verify the feasibility of the hardware designs of this system. The proposed OFDM-based VLC system can process signal in real-time,which can be used in actual VLC application systems.
