Deconstructing the interaural cross-correlation function.
The Journal of the Acoustical Society of America, 2009Because it is a measure of the similarity of signals in a listener’s left and right ears, the long-term interaural cross-correlation (IACC) function within one-third octave bands provides an estimate of auditory envelopment as well as a guide to the ability to localize a sound.

Cross correlation functions in protein dynamics and function.
Journal of Molecular Liquids, 1989Abstract The role of time cross correlation functions induced in liquid water by protein function and dynamics is discussed in the context of recent computer simulations of the gramicidin channel by Swamy and Clementi. On the basis of time autocorrelation functions already computed for this system, such as the orientational and linear velocity auto ...

Filtered FCS and species cross correlation function
SPIE Proceedings, 2009An extended analysis method of time, polarization and color resolved fluorescence correlation spectroscopy (filtered FCS) is introduced. It uses multiparameter fluorescence detection (MFD) [1-3] to separate pure fluorescence signal of multiple species and scatter contributions.

On cross-correlation properties of Boolean functions
2009 Fourth International Conference on Communications and Networking in China, 2009To measure the correlation between two arbitrary Boolean functions, we propose the two new criteria called the sum-of-squares indicator and the absolute indicator of the cross-correlation. The two indicators generalize the GAC criterion (which was proposed by X.M. Zhang and Y.L.

Cross correlation function of wideband MIMO channels
Proceedings of the 6th International Wireless Communications and Mobile Computing Conference, 2010In this paper, we propose a space-time-frequency cross-correlation function (CCF) for multiple-input multiple-output (MIMO) multicarrier channels in a two-dimensional (2D) random scattering outdoor medium. The MIMO channel is considered to be wideband. In our mathematical model CCF is calculated taking into account the clustering phenomenon, frequency ...

The Auto- and Cross-Correlations of Walsh Functions
SIAM Journal on Applied Mathematics, 1977The correlations of Walsh functions are defined and some of their properties derived. One property proved is a recursion relation, which relates correlations of high index functions to those of low index functions. Successive.applications of the equations yield an expression for evaluating the correlations at a restricted value of the time shift.

Identifying cross-correlation peaks with autocorrelation functions
The Journal of the Acoustical Society of America, 1997Crosscorrelating the output of two receivers may fail to provide a means to estimate the arrival time difference of the first arriving signals when the crosscorrelation of accompanying multipaths have amplitudes that may be confused with that between the first arrivals.

Cross-correlation functions for angular momentum and orientation
The Journal of Chemical Physics, 1975A general expression is derived that relates the generalized second moment of a rotational spectral band to an angular momentum−orientation time−correlation function for the ensemble of molecules. It is demonstrated that previous equations relating these spectral transforms to angular momentum correlation functions are recovered in the limit of short ...

On cross-correlation properties of Boolean functions
International Journal of Computer Mathematics, 2011The relationship among cross-correlation of arbitrary four Boolean functions is presented. Several known cross-correlation properties of Boolean functions are generalized. Based on them, a lower bound for the maximal cross-correlation (in absolute value) of two Boolean functions (if one of the functions is bent) is obtained.

Classification of Cross-Correlation Functions for Speaker Localization
2012 International Conference on Computer Science and Service System, 2012Sound source localization plays a crucial role in many microphone arrays application, ranging from speech enhancement to human-computer interface in a reverberant noisy environment. The steered response power (SRP) using the phase transform (SRP-PHAT) method is one of the most popular modern localization algorithms. The SRP-based source localizers have
