Detection of phase randomly distributed weak sinusoidal signal based on double coupled doffing oscillators
Tao Sun · Journal of Chengdu University of Information Technology · 2008
A group of coupled chaotic oscillators is used to achieve the detection of phase randomly distributed weak sinusoidal signal and a new detection method is presented.According to the change of the critical state between the chaos and the period by the single coupled chaotic oscillators the phase randomly distributed weak sinusoidal signal is detected and the phase range can be estimated. It is easier to carry out than the way of a group of coupled chaotic oscillators.
