Abstract
(EN)
The present invention provides a reference signal processing method and device. Said method comprises: taking an RE block as a unit, performing scrambling processing on a first pilot sequence covered by an orthogonal code, so as to generate a second pilot sequence. In the present invention, scrambling processing is performed on the pilot sequence covered by the orthogonal code, and therefore an interference residual part is disturbed by a high frequency, and is eliminated or suppressed easily during subsequent filtering, thereby improving the performance of channel estimation.
(FR)
L'invention concerne un procédé et un dispositif de traitement de signal de référence. Ledit procédé consiste à considérer un bloc RE comme une unité et effectuer un traitement de brouillage sur une première séquence pilote couverte par un code orthogonal de façon à générer une seconde séquence pilote. Selon l’invention, un traitement de brouillage est effectué sur la séquence pilote couverte par le code orthogonal. Par conséquent, une partie résiduelle d'interférence est perturbée par une haute fréquence, puis éliminée ou supprimée facilement lors d’un filtrage ultérieur, ce qui permet d'améliorer les performances d'estimation de canal.

本发明提供了一种参考信号处理方法及装置,该方法包括:以RE块为单位,对正交码覆盖后的第一导频序列进行扰码处理生成第二导频序列。在本发明中,由于对正交码覆盖后的导频序列进行了扰码处理,因此,干扰残余部分会被高频扰乱,在后续的滤波时,容易被消去或抑制,这样则可以提高信道估计的性能。
