2021. Discrete-nonlinear Colpitts oscillator based communication security increasing of the OFDM systems. 2021 International Conference on Electrotechnical Complexes and Systems (ICOECS). :253—256.
This article reports results about the development of the algorithm that allows to increase the information security of OFDM communication system based on the discrete-nonlinear Colpitts system with dynamic chaos. Proposed system works on two layers: information and transport. In the first one, Arnold Transform was applied. The second one, transport level security was provided by QAM constellation mixing. Correlation coefficients, Shannon's entropy and peak-to-average power ratio (PAPR) were estimated.
