Abstract
Chaotic detection is to test weak signals based on trajectory changes of chaotic system. The traditional Duffing system is sensitive to frequency of periodical sine signals, but it is only suitable for detecting low-frequency signals, and can not be used to detect those of high-frequency. Therefore, an improved Duffing system is established in this paper, which is applied innovatively into demodulation process of OOK digital modulation signals. Simulation results by MATLAB show that the chaotic Duffing receiving system can demodulate signal OOK effectively.
