摘要 B 3G移动通信系统可提供高达100Mbit/s的速度,MIMO-OFDM作为B 3G的核心技术,同步问题一直是该系统的关键问题.介绍了正交频分复用技术(OFDM),多输入多输出系统(MIMO)技术的原理,分析MIMO-OFDM系统中存在的同步问题,总结MIMO-OFDM系统的同步方法. The Beyong 3G mobile commumication system could provide 100Mbit/s. MIMO-OFDM was regarded as the core technology of B 3G Sychronization problem is always the key problem of MIMO-OFDM system. Produced the principle of OFDM and MIMO technology, analysed the synchronization problem existing in MIMO-OFDM system., summarized the synchronization method of MIMO-OFDM system.
