摘要：
Based on the theory of Duffing oscillator weak signal detection and the technology of extended binary phase shift keying(EBPSK) modulation, the chaotic demodulator using the Duffing oscillator for EBPSK signals was proposed. The proposed demodulator could avoid the problem of demodulation filters design, and shows the excellent anti-noise capability of chaotic oscillator detection. Numerical and experimental tests were taken to investigate the impact of modulation parameters τ and θ on bit error performance of the proposed method, and the performance limits were gotten. The results show that the proposed chaotic demodulator works well under a very low signal-to-noise ratio(SNR) conditions, and gets SNR gains about 20 d B to 30 d B from the impulse filter.
