摘要
Gram-Schmidt(Gs)正交算法在自适应抗干扰领域日渐被人们所关注,特别是作为一种快速自适应波束形成算法而倍受重视。但采用这种算法需要首先确定信号源的个数,以决定正交化运算的次数。本文正是对此问题进行研究,提出一种简单的方法并利用一个判断阈值来实现在GS正交化过程中自动确定正交化运算的次数。
Gram-schmidt algorithm is an interesting theme in the field of adaptive beamformer as a fast algorithm. However, a key problem associated with this algorithm is the detection of orthogonalisation on the basis of prior-knowledge of interferences dimension. In this paper, a simple and fast approach is proposed to detect the orthogonalisation automatically in the procedure of GS orthogonal decomposition. Finally, computer simulations are presented.
