The Detection Property Analysis of Duffing Oscillator to DPSK Signal

The Duffing oscillator is widely used for BP-SK/DPSK signal detection due to its well detection property. However, the traditional method is not suitable for mobile communication because of the correlation between the primary phases of Duffing oscillator's internal driving force and the undetec...

Description
Summary:The Duffing oscillator is widely used for BP-SK/DPSK signal detection due to its well detection property. However, the traditional method is not suitable for mobile communication because of the correlation between the primary phases of Duffing oscillator's internal driving force and the undetected signal. This paper analyses the response of Duffing oscillator to BPSK/DPSK signal and illustrates the Duffing oscillator's receiving window together with its movement, which is the theoretical base for the construction of Duffing oscillators array operating at same frequency. Meanwhile, the conclusion of detection property for the array with different element numbers is also provided that may help in improving the detection property of engineering applications.
