基于FPGA的OFDM-RoF符号定时同步的实现

摘要

提出了一种在正交频分复用-光载无线(OFDM-RoF)接收系统中符号定时同步算法的设计方案,阐述了该算法在现场可编程门阵列(FPGA)上的实现过程,分析了该设计方案的优势.设计完成后,运用Modelsim SE 10.1c对该算法进行仿真测试并对实验结果进行分析.%This paper proposes a symbol timing synchronization algorithm at the receiver in orthogonal frequency division multiplexing radio over fiber (OFDM-RoF) system,introduces the implementation of the algorithm based on field programmable gate array (FPGA),analyses the advantages of the algorithm.After accomplishment of the design,this paper uses Modelsim SE 10.lc to simulate the algorithm,and analyses the experimental result.
