Simulation of differentially coherent information transmission system based on chaotic radio pulses in ADS environment

Subject of the study. The subject of the work was the study of direct chaotic differentially coherent information transmission scheme based on chaotic radio pulses and its properties. The aim of the work was to carry out circuit simulation of the scheme in order to obtain its characteristics close to the characteristics of real device for the subsequent transition to experiments with physical layouts of differentially coherent transmission scheme. Methods. The circuit simulation was carried out in specialized program environment Advanced Design System (ADS).

An electronic device implementing a strange nonchaotic Hunt–Ott attractor

Topic and aim. The aim of the article is to propose an electronic device representing a non-autonomous dynamical system with a strange nonchaotic attractor insensitive to variation of parameters (with the only limitation that the ratio of the frequencies of the components of the external control driving remains unchanged being equal to a fixed irrational number). Investigated model.

Simple electronic chaos generators and their circuit simulation

Topic and aim. The aim of the work is to review circuits of chaos generators, those described in the literature and some original ones, in a unified style basing on circuit simulations with the NI Multisim package, which makes the comparison of the various devices apparent. Investigated models.
