Abstract: DCS analyzer including a memory to store autocorrelation values, model parameters, fitting parameters, and simulated correlation values from a DCS model; a mean square error (MSE) module to compute MSE between theoretical autocorrelation values computed from the model parameters and measured autocorrelation values; a sorting module to sort three latest MSE values obtained from the MSE module and generate indexes of largest, medium, and smallest MSE values; a convergence checking module to determine whether convergence is reached in solving an autocorrelation equation; a search module to calculate αDB and β values at reflection, extension, contraction, and shrink locations; a comparison module to compare two latest MSE values and find new αDB and β values to replace values associated with a largest MSE; a state controller coupled with the memory and the modules to control an operation thereof; and an output buffer to present a fitted solution of the autocorrelation equation.
