摘　　要：多入多出(MIMO)技术充分利用空间资源,采用多个天线实现信息多发多收,具有频谱利用率高和扩大系统容量的优点,是无线通信领域技术的重大突破,被广泛认为是下一代无线通信系统必须采用的关键技术之一,是解决频谱资源匮乏的有效解决方案。在分析MIMO原理的基础上阐述实现MIMO的关键技术并介绍MIMO技术目前的研究热点与趋势,提出MIMO技术在电力系统应急通信领域中的应用。Multiple-Input Multiple-Output （MIMO）technology makes the best of space resource, adopts multi-antennas for realizing information multi-transmitting and muhi-receiving. This technology has many merits, such as high utilization of frequency spectrum and improved system capacity. MIMO is deemed to one of magnitude technologies in wireless communication region and one of key technologies in next generation wireless communication system. In order to resolve shortage of limited frequency spectrum resource, the basic theory of MIMO was analyzed, the key technologies for realizing MIMO was expatiated and the research hotspots and directions of MIMO were pointed, MIMO technology applied in the field of power system emergency communications was proposed.
