基于软件无线电的智能天线技术

Smart Antenna Based on Softradio

智能天线是第三代移动通信中的重要技术 ,也是当今电信十大热门技术之一 ,它是在软件无线电基础上提出的天线设计新概念 ,是数字多波束形成技术与软件无线电结合的产物 ,它对提高系统容量具有巨大潜力。

Smart antenna is not only an important technology of the third generation mobile telecommunication, but also one of the ten hot telecommunication technologies.It is a new concept of antenna designing on the basis of softradio, and combines the technologies of digital beamforming and softradio .So it is propitious to improve the capacity of wireless communication. In this paper, the structure and algorithm of smart antenna are mainly discussed.
