Another way to estimate cross-correlation between signals is the use of Discrete Fourier Transform (DFT) and the Inverse Discrete Fourier Transform (IDFT) as shown in (8) and (9):
12 shows the product-based average cross-correlation matching values between the predefined autocorrelation pattern and the measured autocorrelation under various wireless channel conditions when an SA signal is transmitted.
We assessed temporal correlations between our time series by using standard estimation of lagged time-series cross-correlations (22) to identify lag times showing the highest correlations between weekly numbers of AEI and ensuing weekly numbers of 1) GBS cases and 2) suspected cases of microcephaly.
Table 1 shows the averaged (across time) peak cross-correlation coefficients for each subject and wavelet band.
We further note two other multiple and significant cross-correlation clusters about the derivative variables.
The cross-correlation analysis (of CORA) between the THOR dummy responses (baseline simulations and experimental tests) and PMHS average responses were presented with average values of Magnitude (Figure 20), Shape (Figure 21), and Phase shift (Figure 22).
According to (1), the SRF is considered as a cross-correlation of the exit slit function and the image function (the convolution result of terms in the square brackets).
Spectrum, cross-correlation, or probability distribution data obtained from electrode Em is expressed as "[E.
As shown in equation (4), the cross-correlations of the 1D active weight TCK codes are k for M = M', O = O', m = m', 0 for M = M', O [not equal to] O', m = m or m [not equal to] m', and 1 for M [not equal to] M', m = m ; that is, the codes have an autocorrelation value of k and have cross-correlation values of 0 or 1.
Well-known families of linear spreading sequences, such as m-sequences, Kasami, Gold, and Walsh codes, traditionally employed as channelization codes, exhibit non-zero and sometime non negligible auto- and cross-correlation out-of-phase values, which limit the achievable performance, in asynchronous or in quasi-synchronous scenarios [11].
The correlational method of pulse optical time domain reflect meter using pseudo random pulse sequence instead of a single pulse, measured by cross-correlation operation of the reference signal and the detection signal.
