Abstract

Abstract: This paper addresses the problem of the analysis of snoring signal with fractals based on wavelet transform.Analysing characteristics of snores signal and detecting its instantaneous pulse are firstly presented.The status is that the variation of snores signal is diagnosed through dynamically analysing its spectrum fractals characteristics.The simulation experiment results show that the proposed method of snores signal based on wavelet transform is obviously advantageous over traditional Fourier transform for analysing the typical non-stable signal.

Key words: wavelet transform, snore, signal analysis, fractals
