An Automatic Recognition Method for the Noise Frequency Modulation Signal

Wang Lei,Zhao Guoqing(ECM Institute,Xidian University,Xi'an 710071,China)  
The thesis presents a detection method for the noise frequency modulation signal using its continuity and accumulation of power spectrum.The signals are automatically recognized by the similarity principle.The theory of PSD detection for the signal of NFM and the similarity principle are analyzed.The NFM signal generation method is given and its frequency spectrum and power spectrum obtained through simulation proves the validity of the method.An analysis of NFM identification probability by using the methods of Monte Carlo is made.The fact is proved that the noise frequency modulation signal can be detected by the similarity principle and the relation between identification probability and accumulation is obtained.
