摘要
首先介绍了智能天线的工作原理, 并以频分双工FDD工作方式为例, 引入了智能天线的核心技术——自适应波束成形系数. 在此基础上, 提出了智能天线前向链路中自适应波束成形系数的产生和频率校准方法. 最后给出了采用频率校准方法后得到的性能改善.
The working principles of the smart antennas are introduced first. Taking the FDD model for example,the key technology of the smart antenna-Adaptive Antenna Weight is presented. Then, the generation method ofthe adaptive antennas weight in the forward link is, in detail, analyzed. At the same time, the improved perfor-mance is gained after employing the frequency calibration method.
