摘要
智能天线是移动通信系统中广泛采用的一种新技术。本文主要介绍在移动通信实验箱中增加智能天线实验功能时对智能天线阵列类型、下行波束赋形、上行波束成形和天线校准等关键算法的选择以及智能天线教学实验系统的整体实现方案。由于实验系统可对信道环境等实验条件做适当简化,因而可以通过合理设计,在不影响实验效果的前提下,降低实验系统的复杂度和成本。
Smart antenna is a widely used new technology in mobile communication system. This paper describes the selection of smart antenna array, key algorithms of uplink and downlink beamforming and antenna calibration. The implementation scheme of smart antenna teaching experimental system into the mobile communications experiment boxes is also included. Some parameters can be simplified in the experimental system so that the complexity and the cost of the experimental system can be reduced by the appropriate design without impacting the experimental effect.
