| 摘 要： | 针对心电信号常被工频干扰污染问题,为了从观测信号中有效分离出心电信号,采用了基于负熵最大化的FastICA方法.仿真中,观测信号由心电信号和工频干扰通过混合矩阵线性叠加而成,无明显心电信号特征.经具体方法基于负熵最大化FastICA方法处理后,分离出的心电信号很好地逼近了理想心电信号,具有明显的心电信号特征,心电信号提...

| Abstract: | Electrocardiogram is always polluted by power interference seriously.FastICA algorithm based on negentropy maximization is introduced to rebuild electrocardiogram from observing signals.In simulation,observing signals are made by linear superposition of electrocardiogram and power interference using mixed matrix,in which characters of electrocardiogram are hardly observed.After using FastICA algorithm,electrocardiogram with obvious characters has been rebuilt successfully,which is a good approximation to original electrocardiogram.So abstraction of electrocardiogram has been done well. |
