Статья посвящена разработке модели когерентной хаотической системы связи, реализующей новый способ модуляции сигнала на основе управляемой симметрии конечно-разностных схем с последующим экспериментальным анализом эффективности различных методов модуляции. Целью работы является проектирование и исследование имитационной компьютерной модели хаотической системы связи с модуляцией сигнала на основе управляемой симметрии полуявных конечно-разностных схем. Элементами научной новизны обладают конечно-разностные модели приемников/передатчиков, позволяющие реализовать новый способ модуляции хаотических сигналов. Результат: получение имитационной модели когерентных хаотических систем связи с инструментами анализа скрытности и помехоустойчивости. Практическая значимость: имитационная модель хаотической системы связи является необходимым инструментом для анализа работоспособности системы перед ее физической реализацией.

The article is devoted to investigation coherent communication system model with a new method of signal modulation based on variable symmetry of finite-difference schemes with subsequent experimental analysis of the effectiveness of different modulation techniques. The aim of the study is to investigate a computer model of chaotic communication system with signal modulation based on variable symmetry of semi-implicit finite-difference schemes. Novelty: elements of scientific novelty have finite-difference models of receivers/transmitters, allowing to realize a new method of modulation of chaotic signals. Result: obtaining a simulation model of coherent chaotic communication systems with tools for covertness and noise immunity analyses. Practical relevance: The simulation model of chaotic communication system is a necessary tool for analyzing the performance of the system before its physical implementation.
