Abstract

Traditional phase detection methods of weak signals have some problems such as high complexity and low accuracy. To cope with these problems,, this paper proposes one novel parallel detection algorithm based on multi-coupled oscillators. Firstly, the chaotic detection model and double coupled oscillator model are studied through EM algorithm. And then, the nonlinear dynamics are studied in-depth, and the noise immunity and stability analyzes of the algorithm are proved in paper. Finally, the weak harmonic power carrier signals simulation results are demonstrated for the effectiveness of the algorithm.
