WebWhat is a Cross Spectral Matrix? Many post-processing beamforming algorithms rely on the Cross Spectral Matrix (CSM) or, more accurately, the cross power spectral density … Webthe CSM. Finally, Section 5 gives a summary. 2. THEORY Let C be an MuM element complex Hermitian cross-spectral matrix contaminated by microphone self-noise contributions on its diagonal. We would like to add an MuM element diagonal matrix D with unknown non-positive diagonal elements dm to cancel the self-noise. Arranging the …

WebCSM kernel has the potential to have a tremendous impact in fields such as neuroscience, where the dynamics of cross-spectrum relationships of LFP signals are of great interest. 7Conclusion This work introduces the cross-spectral mixture kernel as an expressive kernel capable of extracting patterns for multi-channel observations. 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 …
