摘　　要：多入多出(MIMO)技术非常适合在未来无线通信系统中应用。同时,天线选择技术因其能有效地降低MIMO系统的实现成本而受到业界的广泛关注。本文首先阐述了天线选择技术的基本原理,然后分析了该技术在3G长期演进(LTE)系统中工程应用时需要解决的一些问题,最后展望了该技术未来的研究方向和应用前景。Multi-input multi-output （MIMO）technology is very suitable for the future wideband wireless communication systems. Furthermore, the antenna selection technique is widely paid attention to because it can efficiently reduce the implementation cost. In this paper, the basic principle of the antenna selection technique is introduced at first. Then, several necessary issues of its engineering application in third-generation long-term evolution （3G LTE） systems have been analyzed. Finally, its future research directions and promising applications have been envisioned.
