In this thesis the applicability of advanced signal processing techniques to the status distinguishes using heart sound is first demonstrated. Two advanced signal processing techniques namely: algorithm of independent sub-band functions and the heart sound cycle frequency spectrogram. After analyzing the basic characteristics of heart sound signals, the characteristic parameters of heart sound human...
Biometric recognition refers to the automatic recognition of individuals based on their physiological or behavioral characteristics. This paper presents a new biometric identification technique based on heart sounds. It is a signal of benefits recognition by analyzing the basic characteristics of heart sound. For first heart sound signal s1, secondly heart sound signal s2, their characteristic parameters...
This paper presents a new BSS algorithm of single mixed heart voice signal. First the paper discussed the separation model of single-channel heart voice signal and the layered principles. How does this layered work? Can be separated into many layers? The problems are found the solution by to add a reference signal. The equal length layered technique and how to gain independent sub-band functions are...
The paper proposes a new method based on the layered technique and the independent sub-band functions for overcoming some difficult problems of the underdetermined blind source separation in single mixtures signal. The new method needn't use any training data to separate the multisource signals from the single mixed-signal. Based on one-way mixed-signal separation model, the paper brings forward the...
