酉矩阵(Unitary Matrix)是满足条件 ( U^\dagger U = UU^\dagger = E ) 的复方阵,其中 ( U^\dagger ) 是 ( U ) 的共轭转置,( E ) 是单位矩阵。此定义表明,酉矩阵的逆矩阵等于其共轭转置,即 ( U^{-1} = U^\dagger )。例如,单位矩阵、二维复数旋转矩阵均满足这一条件...
Each unitary matrix may be generated (multiplying example) combining the discrete Fourier transform (DFT) matrix and a diagonal matrix by. It is possible to provide feedback using a unitary matrix related to the channel, and to control the transmission over the channel based on feedback obtained...
The difficulty with this transformation is that it is input signal specific–i.e., the matrix ΦT consists of the eigenvectors of the input covariance matrix Rf. It does provide a theoretical limit against which signal-independent transforms (DFT, DCT, etc.) can be compared. In fact, it ...
