Chaotic Communication System with Symmetry-Based Modulation

Communication systems based on chaotic synchronization are gaining interest in the area of secure and covert data transmission. In this paper, a novel digital communication technique coherent transmission approach is proposed. general, resembles well-known modulation nonlinearity parameters. The key idea study to modulate signal by varying not system parameter but symmetry coefficient discrete models obtained special numerical integration method. For purpose, self-adjoint semi-implicit method order 2 used obtain master slave considered oscillator. experimental results explicitly show that, like during modulation, transmitting receiving oscillators may completely synchronize only if coefficients equal both systems. architecture proposed presented. practical applicability confirmed test binary sequence between transmitter receiver preliminary benchmarking system. Since does significantly impact behavior system, its better suitability for messaging was experimentally comparing it with technique.
