Summary:A signal processing device (100) according to an embodiment of the present invention is provided with: a distortion compensating means (101) for subjecting an input signal to distortion compensation processing to compensate for non-linear distortion, and outputting the signal that has been subjected to the distortion compensation processing; an amplifier (102) for amplifying the signal output by the distortion compensating means (101) and outputting the same as a communication signal; and a signal output means (103) for outputting an adjustment signal for adjusting the distortion compensation processing as an input signal to the distortion compensating means (101), at a timing when the communication signal is not being output, where the adjustment signal has a frequency range covering the frequency range of the communication signal. This makes it possible to provide a signal processing device for suppressing a deterioration in an output signal. Selon un mode de réalisation, l'invention concerne un dispositif de traitement de signal (100) pourvu : d'un moyen de compensation de distorsion (101) permettant de soumettre un signal d'entrée à un traitement de compensation de distorsion pour compenser une distorsion non linéaire, puis générer le signal qui a été soumis au traitement de compensation de distorsion ; un amplificateur (102) permettant d'amplifier le signal généré par le moyen de compensation de distorsion (101) et de générer celui-ci en tant que signal de communication ; et un moyen de sortie de signal (103) permettant de générer un signal de réglage pour adapter le traitement de compensation de distorsion en tant que signal d'entrée au moyen de compensation de distorsion (101) à un moment où le signal de communication n'est pas émis, le signal de réglage ayant une plage de fréquences couvrant la plage de fréquences du signal de communication. Cela permet de fournir un dispositif de traitement de signal permettant de supprimer une détérioration d'un signal de sortie. 実施の形態にかかる信号処理装置(100)は、入力信号に対して非線形歪を補償する歪補償処理を行い、歪補償処理がなされた信号を出力する歪補償手段(101)と、歪補償手段(101)が出力した信号を増幅し、通信信号として出力する増幅器(102)と、通信信号が出力されないタイミングで、通信信号の周波数帯域をカバーする周波数帯域を有し、歪補償処理を調整するための調整信号を、入力信号として歪補償手段(101)に出力する信号出力手段(103)を備える。これにより、出力信号の劣化を抑制するための信号処理装置を提供することができる。
