This paper discussed the Doppler spectrum of wireless communication system for high-speed scene, and then proposed an algorithm of active frequency offset correction based on eNode B. The simulation analysis show that the algorithm is realized by active pre frequency offset compensation techniques at the base station side which greatly improved the frequency offset caused by Doppler effect of high-speed mobile environment, and enhanced the user perception in high-speed mobile scenarios.
