一、引言有许多完全不同的算法可以用于自适应波束形成,但大部分文献处理的是梯度下降(GD)算法。梯度下降算法的特点、稳定性以及性能是大家所熟知的。本文强调 Woodbury 恒等(WI)算法。这个名字起因于该算法用了 Woodbury 恒等式(矩阵求逆的辅助定理)。用到 GD 算法 I. INTRODUCTION There are many completely different algorithms that can be used for adaptive beamforming, but most of the literature deal with the gradient descent (GD) algorithm. Gradient descent algorithm characteristics, stability and performance are well known. This article emphasizes the Woodbury identity (WI) algorithm. The name is due to the Woodbury identity (Auxiliary Theorem for Matrix Inversion) used in this algorithm. Use GD algorithm
