摘要:

MIMO OFDM作为一种多天线、多载波传输技术,具有频谱利用率高、抗干扰能力强、传输速度快、传输容量大等特点,目前已经成为4G技术的热门标准之一。但是由于MIMO OFDM系统对频偏和定时比较敏感,因此同步问题的研究显得尤为重要,文中针对目前主流的同步方法做了全面的分析和总结。

关键词: OFDM, MIMO, 时间同步, 频偏估计

Abstract:

As a multi antenna and multi carrier technology,MIMO OFDM has the advantages of high spectrum efficiency,strong anti-interference capability,high transmission speed and large transmission capacity.MIMO OFDM has become one of the most popular standards for 4G technologies.However,due to the sensitivity of the MIMO OFDM system to the frequency offset and timing,the study of synchronization is of great importance.This paper analyzes the current mainstream synchronization methods.

Key words: OFDM;MIMO;time synchronization;frequency offset estimation
