摘　　要：研究了一种基于IEEE802.16e的正交频分复用(orthogonal frequency division multiplexing,OFDM)定时同步算法,结合IEEE802.16e协议定义的OFDM帧结构特点,给出了面向DSP硬件平台的OFDM系统中同步子系统实现方案,最后利用TI公司的TMS320C6416对该方案进行了实现。结果表明,提出的实现方案具有良好的性能。A timing synchronization algorithm of orthogonal frequency division muhiplexing（OFDM） based on IEEE802.16e was studied. According to the characteristics of the frame structure defined in IEEE802.16e standard, a DSP hardware implementation scheme of timing synchronization subsystem was proposed, and the scheme was implemented by using TMS320C6416 of TI Company. The result shows that this implementation scheme has good performance.
