In this paper the cross-correlation and phase-shift techniques are used for material thickness estimation. The cross-correlation is used to measure the time a transmitted signal takes to arrive at the receiver or the time between two successive received signals (multiple echoes). Whereas the phase-shift technique measures the time delay (less than a sine wave period) between transmitted and rec...

Code Division Multiple Access (CDMA) is one of the important radio access technologies for applications in wireless mobile communication systems. A CDMA system requires a large number of suitable spreading sequences having minimum cross-correlation. Many spreading codes have been studied, their cross-correlation values have been found and reported in this paper. Their suitability for applicatio...

A technique for automated terrain corrected SAR geocoding is presented. Instead of operator selected control points the presented method uses cross-correlation with a SAR intensity image simulated from the Digital Elevation Model to refine the geocoding transformation.

We derive sufficient conditions for the cross-correlation coefficient of a multivariate spatial process to vary with location when the spatial model is augmented with nugget effects. The derived class is valid for any choice of covariance functions, and yields substantial flexibility between multiple processes. The key is to identify the cross-correlation coefficient matrix with a contraction m...

Binaural models attempt to explain binaural phenomena in terms of neural mechanisms that extract binaural information from acoustic stimuli. In this paper, a model setup is presented that can be used to simulate binaural detection tasks. In contrast to the most often used cross correlation between the right and left channel, this model is based on contralateral inhibition. The presented model i...

S U M M A R Y We use cross-correlation of seismic noise recorded at stations in the San Andreas Fault Observatory at Depth (SAFOD) pilot hole to extract P and S waves and measure S-wave anisotropy on the horizontal components. The data are recorded at seven three-component stations at depths from 1857 to 2097 m in the pilot hole. In late September and early 2004 October drilling noise underneat...

The foreground component of the X-ray Background (XRB) can be studied by cross-correlating its intensity with galaxy catalogs. We computed the two-point cross-correlation function W xg between 67 Einstein X-ray elds and the APM galaxy catalog. We detected a signal with an amplitude of W xg = :04 :01, signi cant at the 3:5 level. The reality of this signal was tested with a series of control dat...

We propose δ-MAPS, a method that analyzes spatio-temporal data to first identify the distinct spatial components of the underlying system, referred to as “domains”, and second to infer the connections between them. A domain is a spatially contiguous region of highly correlated temporal activity. The core of a domain is a point or subregion at which a metric of local homogeneity is maximum acros...
