An Adaptive Beam Forming Algorithm Based on Smart Antenna System

自适应阵列天线是提高频谱利用率一种可实现的方法。本文提到的自适应波束形成算法主要的优点在于它的简单性和良好的精确度。该算法使用的是接收信号的统计数据,根据接收信号自协方差矩阵最大特征值的特征向量去近似等于目标信号的控制向量。

Adaptive antenna array is an approach that shows real promise for increasing spectrum efficiency. The main contribution of this adaptive beam forming is in its simplicity with a minimal loss of accura- cy. This algorithm uses the statistics of the received signal, the eigenvector corresponding to the maximum eigen value of the auto covariance matrix of the received signal is approximately equal to the steering vector of the target signal source
