WebMay 4, 2024 · It relies on a decomposition of the measured cross-spectral matrix (CSM) using the inherent correlation structure of the acoustical field and of the flow-induced noise. This method is compared with three existing approaches, aiming at denoising the CSM, without any reference or background noise measurements and without any information … WebOct 1, 2024 · We can construct the reduced-rank matrix from the aspect of subspace selection to better match the clutter subspace. In this paper we make use of CSM (cross-spectral metric) method [7] to construct the reduced-rank matrix, which can make the performance of the reduced-rank processing suboptimal. Besides, the subspace …

Webrecorded time signals from the microphone array, a Cross-Spectral Matrix (CSM) is first averaged, and in a second step the CSM is used typically for frequency-domain beamforming. If the measured flow-noise signals are independent stationary stochastic processes, then with increasing averaging time, flow-noise contributions will eventually ... 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 ...
