Due to the use of real value covariance matrix, the proposed algorithms have lower computational complexity when compared with the conventional complex value covariance matrix based MUSIC algorithm.

The algorithm transforms the complex covariance matrix into a real matrix using an unitary transformation and then the real matrix is inversed and eigen-decomposed for adaptive beamforming so it has a low computation complexity in comparison with the ESB adaptive beamforming algorithm.

该算法利用酉变换将复协方差矩阵转换为实矩阵，然后对其求逆和特征分解进行自适应波束形成，因此其运算量比ESB自适应波束形成算法小得多。

The orthogonal projection ( OP) adaptive beamforming algorithm has good performance but it is computationally expensive because of performing eigen-decomposition of the complex covariance matrix.

正交投影（OP）自适应波束形成算法性能优良，但需要进行复协方差矩阵特征分解，运算量大。
