摘　　要：在同态解卷的脉搏系统分析模型的基础上 ,研究了脉搏信号盲解卷的原理。提出了实际可行的算法 ,提取了心脏激励源信号的特征波形。实验结果表明该算法的可行性 ,为脉搏信号的进一步分析提供了依据。The blind deconvolution principle of pulse wave is studied, based on system-analysis model involving homomorphic deconvolution. The feasible arithmetic is given and the characteristic waveforms of heart excitation source is obtained. The experiment results show that this method is effective,supplies further basis to analysis pulse wave.
