cross correlation function meaning in English
互相关函数
互相关系数
Examples
- The time - domain filter can then be used to select the narrow central portion of the cross correlation function ( ccf ) , capturing virtually all of the signal but rejecting most of the noise
对相关函数进行时域滤波，挑选出互相关函数中窄信号自相关函数部分，去掉剩余的大部分噪声能量，得到加窗互相关函数（ ccf ） 。 - Then , base on the determine channel modeling methods , we present a frequency - selective mimo fading channel with von mises probability density function , which is used to characterize non - uniform angle - of - arrival caused by non - isotropic scattering . then we analyze partial cross correlation function of proposed model and proved the model theoretically
然后,通过对其它多入多出信道模型的分析和对比,并基于确定性信道建模方法,建立了一种通用的频率选择性多入多出衰落信道模型,借助“ vonmises ”概率密度函数,以描述非均匀散射体导致的非均匀本地来波方向分布。 - In the first session the fans vibration on - line monitoring system is realized with vc language , also compile auto power spectrum density function , cross power spectrum density function , autocorrelation function and cross correlation function etc spectral analysis function to carry through simple offline fault diagnosis
首先用稳定性强、扩展性好的vc + +语言开发了通风机振动在线监测系统，并编写了自功率谱密度函数、互功率谱密度函数、自相关函数和互相关函数等频谱分析函数来进行简单的离线故障诊断。
