TOPICS
ABSTRACT
In order to use chaotic oscillators to identify Coulter signals with a low SNR (SNR⩽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.
