基于最小互信息原理的机械振动源分离研究

Study on Separation of Mechanical Vibration Based on the Principle of the Minimum Mutual Information

盲源分离技术是近年来出现的一种先进的信号处理方法。该文推导了基于最小互信息原理的自然梯度法,用于机械振动信号源的分离。实验证明,该方法是分离机械振动信号源的一种有效方法。

Method for Blind Separation of sources is the Modern Processing Method for Signal. Based on the principle of the minimum mutual information natural gradient is proposed. which is used separation of signal sources of mechanical vibration, In the experiment, comparison is made among frequency spectral and waveforms of signals before and after separating, which confirms the feasibility of separation mechanical vibration signals by using the referred process.
