摘　　要：超窄带载波信号通常从时域、频域提取的特征对噪声比较敏感。文章应用分形理论,提出了一种对超窄带载波信号提取特征的有效方法,并通过试验实现了信号的识别,介绍了依靠分形理论及相关解调的超窄带传输设备信号发送和提取的实现方法。Abstracted from time-domain and frequency-domain,the characteristics of the super-narrow-band carrier signal is quite sensible to noise.Based on fractal theory,this paper proposes a effective method for the characteristic abstraction of super-narrow-band carrier signal,and realizes signal recognition through experiment.The paper also introduces the method for signal transmission and abstraction of super-narrow-band carrier transmission equipment based on fractal theory.
