Analysis of Doppler frequency shift response mechanism based on OFDM system

摘要：

　　OFDM system is widely used in mobile communication because of its high spectral efficiency and strong anti-multipath capability.However,in high dynamic scenarios,the Doppler shift between the transmitter and the receiver destroys the orthogonality between the sub-carriers,resulting the interference between the sub-carriers and distortion of the signal,which greatly degrades the system performance.In this paper,a mathematical model of Offset-OFDM system was established and the Doppler response formula of OFDM system in high white channel was derived.Furthermore,we investigated the factors that influence the performance of OFDM.This study laid the foundation for determining OFDM system parameters in high dynamic scenarios.
