Title (EN) DISTORTION COMPENSATION DEVICE AND DISTORTION COMPENSATION METHOD
(FR) DISPOSITIF DE COMPENSATION DE DISTORSION ET PROCÉDÉ DE COMPENSATION DE DISTORSION
(JA) 歪補償装置及び歪補償方法
Abstract:
(EN) This distortion compensation device is provided with a first predistorter that compensates for distortion in an amplifier, and a second predistorter that compensates for the distortion in the amplifier and updates a distortion compensation characteristic at a higher frequency than the first predistorter.
(FR) L'invention concerne un dispositif de compensation de distorsion pourvu d'un premier dispositif de prédistorsion qui compense la distorsion dans un amplificateur, et d'un deuxième dispositif de prédistorsion qui compense la distorsion dans l'amplificateur et met à jour une caractéristique de compensation de distorsion à une fréquence supérieure à celle du premier dispositif de prédistorsion.
(JA) 歪補償装置は、増幅器における歪を補償する第1プリディストータと、増幅器における歪を補償し、かつ、第1プリディストータよりも高い頻度で、歪補償特性を更新する第2プリディストータと、を備える。
