一种基于eNode B的主动式频偏校正算法

摘要

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.%针对高速场景下无线通信系统的多普勒频谱问题进行了分析，并提出了一种基于eNode B的主动式频偏校正算法。通过仿真分析：该算法通过在基站侧实现主动式的预频偏补偿技术极大地改善了高速移动场景下多普勒效应引起的频率偏移问题，有效提升了高速移动场景下的用户感知。
