Abstract: front page image
(EN)The present invention relates to an apparatus and a method for improving nonlinearity of a power amplifier in a wireless communication system. A transmission apparatus in a wireless communication system comprises: a transceiver; and an amplifier for amplifying a signal provided from the transceiver, wherein if the power of a signal inputted into the transceiver is smaller than a reference value, the transceiver attenuates the power of the signal by an amount corresponding to the power. In addition, the present invention also includes embodiments different from the embodiment stated above.
(FR)La présente invention concerne un appareil et un procédé destinés à améliorer une non-linéarité d'un amplificateur de puissance dans un système de communication sans fil. Un appareil d'émission dans un système de communication sans fil comprend : un émetteur/récepteur; et un amplificateur destiné à amplifier un signal fourni par l'émetteur/récepteur. Si la puissance d'un signal entré dans l'émetteur/récepteur est inférieure à une valeur de référence, l'émetteur/récepteur atténue la puissance du signal dans une proportion correspondant à la puissance. De plus, la présente invention concerne également des modes de réalisation différents du mode de réalisation cité ci-dessus.
(KO)본 발명은 무선 통신 시스템에서 전력 증폭기의 비선형적 특성을 개선하기 위한 장치 및 방법에 관한 것으로, 무선 통신 시스템에서 송신 장치는 트랜시버(transceiver)와 상기 트랜시버로부터 제공되는 신호를 증폭하는 증폭기를 포함하고, 상기 트랜시버는 상기 트랜시버로 입력되는 신호의 전력이 기준 값보다 작은 경우, 상기 전력에 대응하는 크기만큼 상기 신호의 전력을 감쇠시키는 것을 특징으로 한다. 또한, 본 발명은 상술한 실시 예와 다른 실시 예들도 포함한다.
