摘要 正交频分复用(OFDM)技术是一种高效的调制技术,其基本思想是把串行高速的数据流分散到正交的子载波上进行并行传输,而同步问题是OFDM技术的一个关键问题。给出OFDM系统的模型,对同步问题进行了具体分析,给出载波频率同步的算法的描述,并对基于CP的同步算法进行仿真,结果表明其具有较好的频率捕获能力和较小的误差。 Orthogonal Frequency Division Multiplexing(OFDM) technology is an efficient modulation technology.The basic idea is to distribute the high-speed data stream to orthogonal sub-carrier,and the synchronization is a key issue for OFDM technology.Gives OFDM system model,and analyses the synchronization issues specifically.It also gives the description to carrier frequency synchronization algorithm,and simulates CP-based synchronization algorithms.The result shows that the method has better ability to get the right frequency.It also shows that the CP method has less errors.
