Weak Sine Signal Detection based on Improved Double Differential Oscillators
Han Fe · Journal of Henan Normal University · 2013
In the information detection field,weak signal detection is one of the hot issues in the current study.In order to detect the lower SNR nv-level weak sine signal,considering the sensitivity of detection signals and working stability of chaotic systems,a detection model of improved double differential oscillators was built with differential oscillators restrain to the cycle part of the phase space and Common-mode noise,detecting weak sine signals by the differential waveform.Simulation results show that:the improved differential oscillators can detect weak sine signals better,and the method has the advantage of high stability,high sensitivity,intuitive,and easy to realize,etc.
