Abstract
(EN)
A broadband-carrier frequency-error calculating unit implements, to each of multiple arrangement patterns, accumulative processing that calculates an accumulative value that was accumulated by executing a prescribed processing to an output signal of a DC-AC converting unit at positions of multiple sub-carriers prescribed by the arrangement patterns, while shifting the output signal of the DC-AC converting unit in the carrier direction, in sub-carrier units. The broadband-carrier frequency-error calculating unit also calculates the amount of broadband-carrier frequency-error based on the shift in the carrier direction upon which the maximum value among the accumulative values was calculated, and implements a compensation of the carrier-frequency shift, based on the calculated amount of broadband-carrier frequency-error.

Une unité de calcul d'erreur de fréquence de porteuse large bande exécute, pour chacun de plusieurs schémas d'agencement, un traitement cumulatif qui calcule une valeur cumulative qui a été cumulée en exécutant un traitement prescrit d'un signal de sortie d'une unité de conversion CC/CA en des positions de plusieurs sous-porteuses prescrites par les schémas d'agencement, tout en décalant le signal de sortie de l'unité de conversion CC/CA dans la direction de la porteuse, dans les unités sous-porteuses. L'unité de calcul d'erreur de fréquence de porteuse large bande calcule également l'ampleur de l'erreur de fréquence de porteuse large bande sur la base du décalage dans la direction de la porteuse sur lequel la valeur maximum parmi les valeurs cumulatives a été calculé, et exécute une compensation du décalage de fréquence de porteuse sur la base de l'ampleur calculée de l'erreur de fréquence de porteuse large bande.

 広帯域キャリア周波数誤差算出部は、複数の配置パターンの夫々に対して、当該配置パターンで規定された複数のサブキャリアの位置における直交変換部の出力信号に対して所定の処理を実施することによって累積した累積値を算出する累積処理を、直交変換部の出力信号をキャリア方向に1サブキャリア単位でずらしながら実施し、累積値のうちの最大値が算出されたキャリア方向のずれに基づいて広帯域キャリア周波数誤差量を算出し、キャリア周波数誤差補正部は、算出した広帯域キャリア周波数誤差量に基づいてキャリア周波数ずれの補正を実施する。
