阵列天线最大输出信干噪比下最优权重降维算法

Algorithm of reduced dimension of maximum output SINR in array antenna

本文研究阵列天线系统最大输出信干噪比准则下最优权重的降维算法。在求最优权重的过程中，计算复杂度是我们要关心的重要的问题，而计算复杂度与权重矢量的维数成正比。权重矢量的维数和天线阵的阵元个数相同。在期望方向和干扰方向小于天线阵元个数的情况下，完全可以通过某种变换，降低计算最优权重的实际维数，从而降低计算复杂度。

In this paper, the algorithm of reduced dimension of maximum output SINR in array antenna is deduced. On the condition that the number of expected directions is smaller than that of unexpected directions, the complexity is greatly reduced.
