time correlation

基本解释

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）序列時域相關進行信道粗估計，竝在一個OFDM塊內進行線性內插得到整個OFDM塊內的信道細估計。
Aimed at non-stationary and time-correlation property of the natural speech signals, a new online time-domain blind separation algorithm is proposed for convolutive mixtures of natural speech.
針對語音信號所具有的非平穩性和時域相關性，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屬性對一類代價函數進行推導，獲得一種新的非平穩信號自適應盲分離算法。

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.
