摘　　要：MIMO无线传输技术是通信领域的一项重要技术突破,它能在不增加带宽与功率的情况下成倍地提高无线通信系统的容量和频谱效率,堪称新一代无线通信系统中的关键技术之一,近年来引起了人们的广泛关注与研究兴趣。回顾无线移动通信的发展历程,概述天线分集技术与智能天线技术,剖析MIMO无线传输技术的原理与国内外研究现状:传统单天线系统向多天线系统演进、智能天线向多天线系统演进、MIMO无线传输技术的原理、MIMO系统中的分集与复用、MIMO无线信道建模、MIMO系统中的多天线设计等,为深入认识与进一步研究MIMO无线传输技术奠定基础。Multiple-input Multiple-output Radio Transmission Technology （MIMO RTr）, which has the potential to multiply system capacity and improve spectral efficiency without requiring extra bandwidth and power, becomes an important technical breakthrough and promises to be one of the key technologies for future wireless communication systems, and hence has attracted broad attention and research interests in recent years. This paper reviews the development history of wireless mobile communications, summarizes the antenna diversity and smart antenna technologies, and explores the principles of MIMO R＇Fl＇s and worldwide research trends in this field, including： 1 ） the evolution of both conventional single antenna systems and smart antenna to multiple-antenna systems, 2） the principle of MIMO RTrs, the diversity and spatial multiplexing of MIMO systems, 3） MIMO channel modeling, 4） multiple-antenna design in MIMO systems, and so on. This comprehensive overview of MIMO RTr provides a solid basis for deep understanding and further research of MIMO technologies.
