| 摘 要： | 提出了一种新的用于智能天线中极大抑制干扰的波束形成算法，在干扰信号的导向矢量矩阵的零空间内，经过正交基矢量的线性组合，用最小二乘法求得最接近期望信号导向矢量、并同时对各个干扰信号零陷的权值。与MVDR算法相比，本算法对干扰的抑制更加有效。

| Abstract: | A new beamforming algorithm used in smart antennas, which can greatly depress the interference, is proposed. Within the null space of the steering vectors vectors matrix of interference signals, the weight vector which is closest to the steering vector of the expected signal and deeply depresses the interference signals simultaneously comed be obtained with least square method through the linear combination of orthogonal basis. Compared with the MVDR algorithm, the proposed algorithm is more efficient to depress interference. |
