Csm cross spectral matrix

WebCross spectral density definition as a matrix for three signals i, j, and k. Prediction in the Presence of Noise With Coherence. Cross spectral density is related to a predictive quantity in time series called coherence. The coherence function estimates the extent to which a measurement of y(t) can be predicted using a measurement of x(t) with ... WebAbstract: In high-resolution methods applied to uniform linear arrays (ULA), the preprocessing that consists of forcing the estimated cross spectral matrix (CSM) to be Toeplitz by averaging its elements along its diagonals is known to increase the resolving power drastically. That is why it is always done in practice. However, this approach is …
