Abstract:
(EN) Provided is a wireless device comprising a delay unit, a generation unit and a synthesis unit. The delay unit delays a second transmission signal by just a delay time representing the difference between a time until a first transmission signal passes through the wireless device and a time until the second transmission signal, having a different frequency band than the first transmission signal, passes through the wireless device, a transmission path and another wireless device. The generation unit generates, on the basis of the first transmission signal and the second transmission signal delayed by just the delay time, a cancellation signal corresponding to an intermodulation distortion occurring in the received signal due to intermodulation of the first transmission signal and the second transmission signal at a shared antenna device. The synthesis unit combines the cancellation signal with the received signal that has passed through the shared antenna device and has been input to the wireless device.
(FR) L’invention concerne un dispositif sans fil comprenant une unité de retard, une unité de génération et une unité de synthèse. L’unité de retard retarde un second signal d’émission juste d’un temps de retard représentant la différence entre un laps de temps jusqu’à ce qu’un premier signal d’émission passe à travers le dispositif sans fil et un laps de temps jusqu’à ce que le second signal d’émission, ayant une bande de fréquences différente de celle du premier signal d’émission, passe à travers le dispositif sans fil, un chemin d’émission et un autre dispositif sans fil. L’unité de génération génère, sur la base du premier signal d’émission et du second signal d’émission retardé juste du temps de retard, un signal d’annulation correspondant à une distorsion d'intermodulation se produisant dans le signal reçu en raison d’une intermodulation du premier signal d’émission et du second signal d’émission au niveau d’un dispositif d’antenne partagée. L’unité de synthèse combine le signal d’annulation avec le signal reçu qui est passé à travers le dispositif d’antenne partagée et est entré dans le dispositif sans fil.
(JA) 無線装置は、遅延部と、生成部と、合成部とを有する。遅延部は、第1の送信信号が無線装置を通過するまでの時間と、第1の送信信号とは周波数帯が異なる第2の送信信号が無線装置、伝送路及び他の無線装置を通過するまでの時間との差を示す遅延時間だけ第2の送信信号を遅延させる。生成部は、アンテナ共用器における第1の送信信号及び第2の送信信号の相互変調によって受信信号に発生する相互変調歪みに対応するキャンセル信号を、第1の送信信号と、遅延時間だけ遅延された第2の送信信号とに基づいて生成する。合成部は、アンテナ共用器を通過して無線装置へ入力される受信信号にキャンセル信号を合成する。
