A new data-hiding algorithm for multi-channel biomedical signals based on variable-order fractional chaotic neural networks with frequency effect

In this study, a new variable-order fractional chaotic neural network with frequency effect is proposed based on Hopfield Neural Network Under Electromagnetic Radiation, which is used to model brain functions in the literature. The numerical solution of this proposed system is carried out by the Grunwald–Letnikov (G–L) method, and time series and phase portraits are presented. In addition, the chaotic behavior is analyzed by Lyapunov exponent...
