A novel dissipative and conservative megastable oscillator with engineering applications

摘要

In this paper, we have proposed a new chaotic megastable oscillator which has both conservative and dissipative characters depending on the selection of parameters. Various dynamical characteristics including megastability of the new system are investigated and presented. The bifurcation plots and the corresponding Lyapunov exponents (LEs) confirm the existence of both dissipative and conservative oscillations in the system. The proposed megastable oscillator is used as a carrier generator in a differential chaos shift keying (DCSK). Another application of the new chaotic oscillator is shown by using it in developing a random number generator (RNG) and the NIST test results are presented to show the statistical complexity of the new system.
