频率同步是宽带OFDM系统中的关键技术，IEEE 802.11a 采用OFDM技术，利用其前导序列的重复结构，提出了一种分步的粗细频偏捕获与校正算法，同时为了补偿时域同步后的残余相差和适应信道的时变特性，还提出了一种基于频域导频的相位跟踪方案-Frequency synchronization is a key technology in the broadband OFDM systems, IEEE 802.11a uses OFDM technology, the use of the repetitive structure of the leader sequence, the thickness of a step frequency offset capture and correction algorithm, when the order to compensate at the same time domain synchronous residualthe difference between and adapt to the time-varying characteristics of the channel is also proposed based on frequency domain pilot phase tracking scheme
