说明： 在研究了超高速OFDM系统传输模型的基础上，对OFDM系统的传输信号结构进行了分析，结合传统的多普勒频移算法，用OFDM信号循环前缀所包含的相对频偏信息设计了实时性较好的多普勒频移估计方法，并分析了多径效应对于循环前缀数据的“污染”效应，对该算法进行了优化，提高了算法的频移估计性能，并对该算法进行了性能验证。
(Based on the study ultra-high-speed transmission of OFDM system model, the OFDM signal structure for the transmission system is analyzed, combined with traditional Doppler shift method, the relative deviation OFDM signal with cyclic prefix information contained in the real-time design Doppler shift better estimation methods, and analyzes the " pollution" effect of multipath effects for cyclic prefix data, the algorithm has been optimized to improve the frequency estimation algorithm performance and the performance of the algorithm verification.)
