相乘信号 meaning in English
multiplying signal
Examples
- In the aspect of blind - identification , the mutual power spectrumx time - frequency distribution product of two delay signals are used as the features of classification . the cluster analysis and cumulant invariants of mpsk signals are used to automatically classify communication signals
在信号识别中，选取信号的互功率谱、时频分布、 mpsk信号的延迟相乘信号作为分类特征，利用模式识别中的聚类分析以及mpsk信号的基于高阶累积量构成的分类特征不变量实现了信号调制类型的自动分类。
