product moment method的意思|示意

The method with different order amplitude moments makes use of the product moment of signal magnitude for classification of MPSK/MQAM signals.

不同阶幅度矩进行调制分类的方法利用MPSK/MQAM信号每符号段波形起始点与其它点幅度的乘积统计矩特征进行调制分类。

Moreover, the applications of this method to feature extraction of cepstrum product and spectral moment distance are described.

此外，本文应用这种方法提取语声倒谱的积谱、谱矩距离等语音时变特征，并加以伪彩色编码显示。
