[FDOUT, FREQ_AXIS] = FDCORR(A,B,FRANGE)FDCORR Joint frequency and delay correlation Performs an efficient circular cross correlation between two vectors over all possible frequency offsets (Dopplers) between -pi and pi where 2pi is the sampling rate.A: vector representing received signal sampled...

Uses fft to calculate the circular cross correlation of two periodic signal vectors.This is equivalent to xc(k)=sum(u1.*circshift(u2,k)), but much faster (on the order of 500 times faster for a 1024 point signal).The package also includes two examples. One checks the calculation against the...

A package of Matlab functions for exploring spatial patterns of correlation in high resolution climate data. Cross-similarity parameters (dominant lag, max-similarity, window cross-similarity) are calculated for each pair of records and presented on maps as well as plots with an intersite...

This code calculates the cross-correlation for specified time windows over the duration of two input signals. The time windows can be shifted by increments smaller than the time window length. The code is based upon the 'xcorr' function.


Platforms: Matlab

The program takes the columns of an input matrix and calculates the auto and cross correlation of these columns using an fft method. The result is very similar to the xcorr function. This method could be used to evaluate the cross correlation of repeating code sequences, and other similar...

AMI computes and plots average mutual information (ami) and correlation of univariate or bivariate time series for different values of time lag.USAGE: [amis corrs] = ami(xy,nBins,nLags)INPUT: xy: either univariate (x) or bivariate ([x y]) time series data. If bivariate time series are given then...

The correlation function calculated from one realization of an ensemble is inherently flawed since the expectation operation does not come into play. Hence it is important to have an idea of the variance in the correlation function.
