摘要: 针对鼾音信号的特点,提出一种利用小波奇性检测原理的方法,以MATLAB 仿真为基础,不但给出分析鼾音信号不同频段特征的仿真结果,又对信号奇异性进行了检测,确定了奇异性的位置和奇异性指标。结果表明,该方法给分析异常鼾音信号或医疗诊断提供了非常有价值的信息。

Abstract: A new way to signal of snore is discussed in this paper,which using wavelet singularity detection based on MATLAB simulation analysis,and it not only shows the simulation result of analyzing the character of different frequency snoring signal,but also checks signal singularity,and points out its position and Lipschitz index.This fact demonstrates that the method may offer the important message of analyzing singularity signal or diagnose of medical treatment.

Key words: wavelet transformation, snore, signal singularity, wavelet singularity detection, spectrum analysis
