The purpose of this paper is to analyse the statistical characteristics a Direct Chaotic Differentially Coherent communication scheme based on chaotic radio pulses in channel with additive white Gaussian noise, where signal given by different instantaneous distributions. Methods. To achieve goal, numerical modelling noise immunity conducted and compared results analytical research. Results. reg...

To improve the noise immunity, stability and sensitivity to different signal types in hydroelectric unit fault diagnosis model, a model based on improved multiscale fractional-order weighted permutation entropy (IMFWPE) is proposed. Firstly, fractional order weighting theory introduced into (PE) signals while improving defect of ignoring amplitude information. Additionally, considering problem ...

Random noise polarimetry is a new radar technique for high-resolution probing of subsurface objects and interfaces. The University of Nebraska has developed a polarimetric random noise radar system based on the heterodyne correlation technique. Simulation studies and performance tests on the system confirm its ability to respond to phase differences in the received signals. In addition to polar...

The research method consists in applying the state space method, widely used study of automatic dynamical systems, to describe behavior cognitive systems. It is assumed, that at input system, there a signal and interference described by Poisson point processes, modeling amount information, emotional stress, etc., corresponding each event. properties system paper are taken into account two circu...

The most widely used architecture in large-area amorphous silicon (a-Si) flat panel imagers is a passive pixel sensor (PPS), which consists of a detector and a readout switch. While the PPS has the advantage of being compact and amenable toward high-resolution imaging, reading small PPS output signals requires external column charge amplifiers that produce additional noise and reduce the minimu...

Developing automotive electronic control units (ECUs) or sensors requires thorough immunity tests to prevent them from malfunctions caused by onboard or external electromagnetic noise. To reduce the development costs and time from repeating those tests, EM noise tolerance design at the design stage is important. If the estimation of intruding noise from wire harness into ECU or sensor becomes p...
