A Comparison Investigation of Demodulation Techniques for Chaotic Modulation Communication Systems

YANG Bo,SUN Wei-wei,FENG Jiu-chaoSchool of Electronic and Information Engineering,Southwest University,Chongqing 400715,China  
Chaos-based wideband communication is an interesting topic,in which chaotic modulation and demodulation is an important realizing technique.Combining adaptive filtering algorithm with adaptive demodulation algorithm,several demodulation techniques of chaotic modulation communication systems are studied comparatively.The results by computer simulation indicate that the demodulation method by using the combined adaptive filtering and adaptive demodulation algorithms can effectively reduce channel's noise and recover message signals.
