信号自相关 meaning in English

signal autocorrelation

Autocorrelation algorithm for speech pitch detection based on matlab
的语音信号自相关基音检测
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 ）。
Because the adaptive algorithm of conventional adaptive noise canceller is the least mean squares ( lms ) , and the convergence rate of lms is heavily dependent on the eigenvalue distribution of the autocorrelation matrix of the input signal , thus lms converges at unacceptably low rates when the input signal is colored noise or speech
由于传统自适应噪声抵消系统( anc )自适应算法主要采用lms算法，而lms算法收敛速度依赖于输入信号自相关矩阵特征值的分散程度。因此，当输入信号是语音或有色噪声时， lms的收敛速度很慢。
