摘要
正交投影变换及其矩阵在信号处理问题中有着广泛应用,因此对正交投影及其矩阵进行了研究,给出了酉空间Cn到其子空间的正交投影σ在某基下的特殊矩阵表现形式。
Orthogonal projection matrix and its transformation have been extensivelg applied in signal process. This paper discusses orthogonal projection matrix and gives out a specific matrix expressive form of orthogonal projection of Unitary space to its subspace on a certain basis.
