Lifeng Wei, Mingxin Liu, Beiming Li · 2019
In the paper, the algorithm of digital communication system of Duffing oscillator is introduced. The first step is to design a quantitative detection method for the phase realization of Duffing oscillator of digital communication system. From the specific application to the engineering practice, it has the characteristics of being able to qualitatively judge the phase state quickly and easily, and can quantitatively analyze and quantify it. A scheme based on the Runge-Kutta algorithm for system parameter of phase is proposed.
