Robust Adaptive Beamforming Based on Low-Rank and Cross-Correlation Techniques [PDF]
IEEE Transactions on Signal Processing, 2016 This paper presents cost-effective low-rank techniques for designing robust adaptive beamforming (RAB) algorithms. The proposed algorithms are based on the exploitation of the cross-correlation between the array observation data and the output of the ...

Multiscaled Cross-Correlation Dynamics in Financial Time-Series [PDF]
, 2008 The cross correlation matrix between equities comprises multiple interactions between traders with varying strategies and time horizons. In this paper, we use the Maximum Overlap Discrete Wavelet Transform to calculate correlation matrices over different

ROBUST TESTS FOR WHITE NOISE AND CROSS-CORRELATION
Econometric Theory, 2019 Commonly used tests to assess evidence for the absence of autocorrelation in a univariate time series or serial cross-correlation between time series rely on procedures whose validity holds for i.i.d. data.

On the correlation structure of microstructure noise in theory and practice [PDF]
, 2008 We argue for incorporating the financial economics of market microstructure into the financial econometrics of asset return volatility estimation. In particular, we use market microstructure theory to derive the cross-correlation function between latent ...

Analysis of vibration and acoustic signals for noncontact measurement of engine rotation speed [PDF]
, 2020 The non-contact measurement of engine speed can be realized by analyzing engine vibration frequency. However, the vibration signal is distorted by harmonics and noise in the measurement.
