An approach is proposed to the filtering of an additive mixture ultra-wideband chaotic signals and white Gaussian noise, in order retrieve useful signal receiver. The role filter performed by a passive frequency-selective circuit, identical one involved formation oscillations chaos generator. A mathematical model modulating generator, detecting receiving sequence radio pulses noisy channel desi...

Abstract. This paper is devoted to the study of mean-field limit for systems of indistinguables particles undergoing collision processes. As formulated by Kac [22] this limit is based on the chaos propagation, and we (1) prove and quantify this property for Boltzmann collision processes with unbounded collision rates (hard spheres or longrange interactions), (2) prove and quantify this property...

An original scheme for constructing an ultra-wideband single-transistor generator of noise-like oscillations the microwave range wavelengths was proposed. The contains inertial converter output signal a nonlinear amplifier with positive feedback, which modulates supply voltage active element (transistor). experimental model chaotic based on powerful domestic transistor 2T982A-2 operating in sma...

With the increasing wind power penetration, farms are directly influencing systems, so need to improve quality of system is an open research topic. A Doubly-Fed Induction Generator (DFIG) often used in systems. However, DFIG has a complex structure and works harsh environments, potential faults may occur. Faults can cause fall into chaotic working state, which harmful phenomenon for DFIG, since...

The ultra wide band (UWB) Direct Chaotic Communication (DCC) technology is considered in application to low bit rate information transmission. Performances of low bit rate DCC are discussed. In particular we pay attention to the effect of multipath processing. The implementation and experimental verification of basic elements for low bit rates DCC are also presented. Index terms – Ultra wide ba...

A three-transistor CMOS circuit is presented, with adjustable nonlinear characteristics, which can be used as a map that generates discrete-time chaotic signals. A method of constructing a chaos generator using two map circuits is also proposed. The circuit is very compact, which makes it suitable for applications requiring the integration of a large number of random signal generators on a sing...

This letter describes a novel family of frequency hopping sequences generated by chaotic systems. The sequences give a uniform spread over the entire frequency bandwidth. In addition to having good Hamming correlation properties, they possess ideal linear span. The sequences produce almost as good performance as random hopping patterns when used in frequency hopping code-division multiple-acces...

A new method of improving the properties of number sequences produced by a multiplicative congruential pseudorandom generator (MCPG) was proposed. The characteristic feature of the method is the simultaneous usage of numbers generated by the sawtooth chaotic map, realized in a finitestate machine, and symbols produced by the same map. The period of generated sequences can be significantly longe...
