Abstract: front page image
(EN)Disclosed is a corrected transmission line estimating device for removing the leakage of a side lobe component between transmission lines from an estimated transmission line value, thereby to enhance precision. A transmission line estimating unit determines the estimated transmission line values of a plurality of transmission lines from signals to arrive through multipaths. A transmission line estimation correcting unit removes the leakage of the side lobe component between the transmission lines from the estimated transmission line value determined by the transmission line estimating unit, thereby to correct the estimated transmission line value. Thus, the correction transmission estimating device estimates the transmission line of the multipaths.
(FR)L’invention concerne un dispositif d’estimation de ligne de transmission corrigée permettant de supprimer la fuite d’une composante de lobe latéral entre les lignes de transmission à partir d’une estimation de valeur de ligne de transmission, pour ainsi augmenter la précision. Une unité d’estimation de ligne de transmission détermine les valeurs d’estimation de ligne de transmission d’une pluralité de lignes de transmission à partir de signaux pour emprunter des trajets multiples. Une unité de correction d’estimation de ligne de transmission supprime la fuite de la composante de lobe latéral entre les lignes de transmission à partir de l’estimation de valeur de ligne de transmission déterminée par l’unité d’estimation de ligne de transmission, pour ainsi corriger l’estimation de valeur de ligne de transmission. Ainsi, le dispositif d’estimation de transmission de correction estime la ligne de transmission des trajets multiples.
(JA) 伝送路推定値から伝送路相互のサイドローブ成分の漏れ込みを除去して精度を上げることのできる補正伝送路推定装置が開示される。伝送路推定部は、マルチパスで到達する信号から複数の伝送路の伝送路推定値を求める。伝送路推定値補正部は、伝送路推定部で求められた伝送路推定値から、伝送路相互のサイドローブ成分の漏れ込みを除去して、伝送路推定値を補正する。これにより補正伝送路推定装置はマルチパスの伝送路を推定する。
