摘 要: | 盲源分离作为一种基于主向量分析的信号处理方法,目的是通过假设源信号之间的统计独立性,由一组观测信号恢复出源信号。研究了盲信号分离理论,尤其是盲卷积分离,采用基于交叉残余误差RCTE控制准则的盲分离算法,并针对旋转机械振动信号的特点生成仿真信号,将该方法应用于旋转机械振动信号瞬态成分与噪声卷积混合问题,仿真试验结果表明了该算法的有效性。

Research on rotating mechanical vibration by blind source separation |

Abstract: | Blind Source Separation(BSS) is a signal processing method based on independent component analysis,its aim is to separate the source signals from a set of observations by assuming the signals independently.Reviews the general concept of BSS,especially the theory for convolutive mixtures,and then presents a BSS algorithm for convolutive mixtures based on residual cross-talking error threshold control criteria,the simulation testing points out good performance for separation of rotating mechanical vibration s... |
