摘要
论述了现有系统面临着提高系统容量和改善通信质量的双重压力，而智能天线技术引入空分多址的概念，能够有效地提高系统容量。分析了智能天线技术的原理；给出了两种时分多址系统中的智能天线系统结构和比较；介绍了智能天线技术中的自适应波束合成算法。
The existing system has the double pressure of both increasing system capacity and improving communications quality． Smart antenna system introduces the concept of space division multiple access SDMA and can increase effectively system capacity． This paper analyses smart antenna technology principle gives the smart antenna system structure of two types of SDMA system and their comparison introduces adaptive beam composition algorithm of smart antenna technology．
