摘要 本文给出了AR模型MEM法的基本理论,通过实例证明这种方法得到的功率谱出较光滑,并且不需要预先知道信号的频率幅值等信息,适合于不以信号处理为研究方向的科研人员和现场操作人员用来分析轧机信号。 The basic theory of MEM method based on the AR model was given in this article. It was proved that the Power Spectral Density gotten by this method is smooth and information of signals such as frequency, amplitude was not needed previously. This method is suitable to scientific researchers and operates who not to make signal pr℃ essing as their research field.
