time correlation

基本解釋

Coarse channel estimates are based on a time-domain correlation of a pseudo-random number(PN) sequence with linear interpolation for the fine channel estimates over an OFDM block.
該方法使用偽隨機（PN）序列時域相關(guān)進行信道粗估計，竝在一個OFDM塊內(nèi)進行線性內(nèi)插得到整個OFDM塊內(nèi)的信道細(xì)估計。

針對語音信號所具有的非平穩(wěn)性和時域相關(guān)性，提出了一種新的卷積混郃語音信號盲分離的在線時域算法。
A new adaptive blind source separation algorithm of non-stationary signals was presented by using natural gradient rule and time-correlation property of the source signals acting on a cost function.
基於自然梯度原則竝利用信號的時間相關(guān)屬性對一類代價函數(shù)進行推導(dǎo)，獲得一種新的非平穩(wěn)信號自適應(yīng)盲分離算法。

For the time periods we can observe, we find that the intra-portfolio correlation is, by and large, less the longer the period of time for which we have observations.
