摘要
介绍了智能天线技术及其在TD-SCDMA系统中的应用.通过对阵元接收信号加权处理,形成天线波束,使天线主波束对准用户信号到达方向,旁瓣或零陷对准干扰信号到达方向,可达到抑制干扰、提高接收灵敏度的目的.使用智能天线可以在不显著增加系统复杂程度的情况下扩充容量、加大覆盖范围、降低误码率.
This paper introduces the smart antenna technology and its application in TD-SCDMA system. Through processing signals received by the array element in weighted way to form antenna beams, smart antennas let the antenna's major lobe point to the coming direction of reference user and the side lobe point to the coming direction of interference user and suppress interference and improve receiving sensitivity. Using smart antenna can expand capacity, enlarge coverage area and reduce error rate in the case of not increasing system complexity indistinctively.
