翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク autocorrelation matrix ： ウィキペディア英語版 autocorrelation matrix The autocorrelation matrix is used in various digital signal processing algorithms. It consists of elements of the discrete autocorrelation function, $R\_(j)$ arranged in the following manner: :$\backslash mathbf\_x\; =\; E()\; =\; \backslash begin$ R_(0) & R^ *_(1) & R^ *_(2) & \cdots & R^ *_(N-1) \\ R_(1) & R_(0) & R^ *_(1) & \cdots & R^ *_(N-2) \\ R_(2) & R_(1) & R_(0) & \cdots & R^ *_(N-3) \\ \vdots & \vdots & \vdots & \ddots & \vdots \\ R_(N-1) & R_(N-2) & R_(N-3) & \cdots & R_(0) \\ \end This is clearly a Hermitian matrix and a Toeplitz matrix. If $\backslash mathbf$ is wide-sense stationary then its autocorrelation matrix will be positive definite. The ''autocovariance matrix'' is related to the autocorrelation matrix as follows: :$$ \mathbf_x = \operatorname (- \mathbf_x)(\mathbf - \mathbf_x)^H ) = \mathbf_x - \mathbf_x\mathbf_x^H Where $\backslash mathbf\_x$ is a vector giving the mean of signal $\backslash mathbf$ at each index of time. == References == * Hayes, Monson H., ''Statistical Digital Signal Processing and Modeling'', John Wiley & Sons, Inc., 1996.
