相关积分 meaning in English
correlation integral
Examples
- Two approaches to improve the robustness of the detector , each based on a different theirs distortion mechanism . one is based on the modeling as fast fading distortion ( ffd ) whose optimum detector is the segmented replica correlator ( src ) . the second approach is replica correlation integration ( rci ) for time spreading channel ( tsd )
从频率扩展信道( fastfadingdistortion ， ffd )和时间扩展信道( timespreadingdistortion , tsd )的形成机理出发建立了目标回波的数学模型，指出ffd和tsd的最佳检测器分别为分段副本相关器( src )和副本相关积分器( rci ) 。 - At the same time , the optimum detector of ffd and tsd in wavelet domain have been investigated according to properties of cwt . they are wavelet - domain - segmented - replica - correlator ( wdsrc ) and wavelet - domain - replica - correlation - integration ( wdrci ) . and we have proved that their performances are consistent with those in time domain
同时又依据连续小波变换的性质推导出ffd和tsd信道小波变换域的最佳检测器：小波域的分段副本相关器( wdsrc )和小波域的副本相关积分器( wdrci ) ，并从理论和仿真证明了它们与相应的时域检测器性能的一致性，优于小波域的副本相关器( wdrc ) 。 - The analysis methods that the system adopts are introduced from the view of time - domain , frequency - domain and time - frequency - domain . emphasis is focused on the correlation integral analysis method . the measurement parameter of signal nonstationarity defined on the basis of correlation integral is discussed , and the feasibility that it is used to diagnose the faults of dynamic nonstationarity as the characteristic parameter is also investigated with a case
