Signal processing is the critical device and technology support for software radio, so it is very important to evaluate the efficiency of signal processing in software radio. In this article, I propose a cross-correlation criterion, in which correlation operator is its theory foundation, correlation...
Definition: The circular cross-correlation of two signals and in may be defined by (Note that the ``lag'' is an integer variable, not the constant .) The DFT correlation operator `' was first defined in §7.2.5. The term ``cross-correlation'' comes from statistics, and what we hav...

The true cross-correlation sequence is where xn and yn are jointly stationary random processes, −∞ < n < ∞, and E {·} is the expected value operator. xcorr must estimate the sequence because, in practice, only a finite segment of one realization of the infinite-length random process ...

Analysis: Finding the maximum correlation is straightforward: apply MATLAB’s max operator to the crosscorrelation function. Finding the time at which the maximum value occurs is a bit more complicated. The max operator provides the index of the maximum value, labeled here as max_shift. To find...

We study the effects of correlations between additive and multiplicative noise on relaxation time in a bistable system driven by cross-correlated noise. Using the projection-operator method, we derived an analytic expression for the relaxation time T(c) of the system, which is the function of ad...
Cross-correlation in particle image velocimetry is well known to behave as a non-linear operator, depending heavily on the distribution of tracer images and image quality. While analytical descriptors of the correlation response have so far been dealt with for simplistic flow cases, in this work ...
