APPLICATION OF A RING COUPLED DOUBLE-DUFFING OSCILLATOR TO A SCHEME FOR IDENTIFYING THE COULTER SIGNAL WITH A LOW SNR

In order to use chaotic oscillators to identify Coulter signals with a low SNR (SNRG 0), a Gaussian pulse signal is used to simulate the Coulter signal, and we study the continuous synchronous mutation (CSM) phenomenon of a chaotic ring coupled double-Duffing (RCDD) oscillator to identify the signals. The maximum difference between the two state variables in the oscillator can be used to determine the anti-noise ability of the oscillator and construct a function to identify pulse amplitudes. A Simulink model is constructed to verify that the proposed method can be used to identify pulse amplitudes with a low SNR, which provides an approach for developing a technology of measuring Coulter signals with the low SNR.

Automated summary

To identify Coulter signals with low SNR using chaotic oscillators, a Gaussian pulse signal is used to simulate the signals, and the continuous synchronous mutation phenomenon of a chaotic ring-coupled double-Duffing oscillator is studied for signal identification. The maximum difference between the oscillator's state variables can determine its anti-noise ability and be used to construct a function for identifying pulse amplitudes. A Simulink model confirms that this method can successfully identify pulse amplitudes with low SNR, providing an approach for measuring Coulter signals with low SNR.
