摘　　要：提出了一种基于心音信号谱分析的生物识别方法。首先对心音信号进行消噪预处理,然后利用最大熵谱方法提取出心音信号的谱系数特征,采用欧式距离作为匹配算法完成身份识别。实践证明该方法是提取心音信号唯一性特征的有效方法。This paper proposes an algorithm to extract the feature of heart sound based on frequency analysis. The spectral coefficient of heart sound was extracted after pre-processing of it. Then the Euclidean distance was used to measure the distance between the signal spectra. Finally, the result, obtained from a database that containing several heart sound recording form different people, confirm the validity of the proposed method.
