摘　　要：大规模多输入多输出正交频分复用(Multiple Input Multiple Output Orthogonal Frequency Division Multiplexing,MIMO-OFDM)技术是5G的核心技术之一。本文针对大规模MIMO-OFDM系统的同步问题,提出了一种基于训练序列的同步方法。该方法结合特殊的Park训练序列结构,将训练序列分为四个部分,通过对训练序列结构进行相关计算来求得系统的频率偏移值。仿真结果表明,该方法可以有效提高大规模MIMO-OFDM系统的同步性能。Massive multiple input multiple output orthogonal frequency division multiplexing(MIMO-OFDM)systems is one of the core technologies of 5G.This paper proposes a synchronization method which based on training sequence for massive MIMO-OFDM systems.The method combines the special Park training sequence structure,divides the training sequence into four parts,and obtains the frequency offset value of the system through correlation calculation of the training sequence structure.Simulation results show that this method can effectively improve the synchronization performance of large-scale MIMO-OFDM systems.
