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.
