摘要 MIMO与OFDM技术的结合,有效对抗频率选择性衰落、提高数据传输速率、增大系统容量,是第四代移动通信系统研究的热点问题。本文介绍了4G移动通信中的MIMO-OFDM的基本原理及MIMO-OFDM系统的关键技术包括信道估计、同步、空时编码技术和分集技术。 The combination of MIMO with OFDM would overcome the frequency selective fading, raise the data transmission rate and improve the system capacity. And it is the hotspot for the research of 4G Mobile Communication System. This paper describes the principle and key techniques of the MIMO-OFBM in 4G, including the channel estimation, synchmnization technique, space-time coding and diversity technique.
