Demodulation of ASK signal based on chaotic oscillator

GAO Qing Shan,ZHANG Tian Qi,JIANG Shi Wen,HUANG Yao (Chongqing Key Laboratory of Signal and Information Processing,Chongqing University of Posts and Telecommunications,Chongqing 400065,China)  
Chaotic oscillator has characteristic of sensibility to small periodic signals and immunity against noise.By making use of the characteristic,a new method of demodulating ASK signal submerged in strong noise is presented according to the demodulation problem of weak digital modulation signal.Technique of weak signal detection based on Duffing oscillator is introduced first.By combining with modulation method of ASK signal,the basic idea of demodulating ASK signal using duffing oscillator is analyzed,and a new method is presented for power spectrum entropy used to judge the system state.The simulation show that ASK signal could be demodulated at by the method presented here and the anti noise performance is better than traditional demodulation method.
