Abstract:
The new class of nonlinear radio-electronic dynamic systems with dynamic chaos on the basis of their updating with time step-size modulation is considered. Perfection and depreciation of digital element base does actual realization of shapers of multilevel chaotic signals on the basis of algorithms of the numerical decision of systems of the differential equations describing systems with dynamic chaos. Thus the grid time step makes essential impact on characteristics of formed signals. In article the analysis of statistical characteristics of a new class of nonlinear radio-electronic dynamic systems with changeable grid time step is carried out. Influences of static change and modulation of grid time step on correlation characteristics of formed signals are investigated. Approximation of signals probabilities density of the offered nonlinear systems with dynamic chaos of poly-Gauss statistics is spent. It is shown, that signals probabilities distributions of systems probably to approximate three-componential poly-Gauss statistics an error not exceeding of 20 %.
