Abstract:
(EN) An electronic device according to various embodiments of the present invention comprises: a transceiver; a power amplifier; at least one antenna; a coupler; a memory for storing reference phase information; and a processor. The processor may be configured to: transmit an output signal of a designated frequency band by using the transceiver; amplify the output signal by using the power amplifier; radiate the amplified output signal via the at least one antenna; acquire, via the coupler, the amplified output signal and a reflected signal that is the amplified output signal having been reflected from the at least one antenna; identify a reflection coefficient on the basis of the amplified output signal and the reflected signal; on the basis of phase information corresponding to the reflection coefficient, identify a difference value between the phase information corresponding to the reflection coefficient and reference phase information, among items of reference phase information, corresponding to the designated frequency band; and compensate for another output signal to be transmitted through the transceiver, at least on the basis of the difference value. In addition, various embodiments are possible.
(FR) Divers modes de réalisation de la présente invention concernent un dispositif électronique comprenant : un émetteur-récepteur ; un amplificateur de puissance ; au moins une antenne ; un coupleur ; une mémoire servant à stocker des informations de phase de référence ; et un processeur. Le processeur peut être conçu pour : transmettre un signal de sortie d'une bande de fréquence désignée à l'aide de l'émetteur-récepteur ; amplifier le signal de sortie à l'aide de l'amplificateur de puissance ; rayonner le signal de sortie amplifié par le biais de ladite antenne ; acquérir, par le biais du coupleur, le signal de sortie amplifié et un signal réfléchi qui est le signal de sortie amplifié ayant été réfléchi par ladite antenne ; identifier un coefficient de réflexion sur la base du signal de sortie amplifié et du signal réfléchi ; en se basant sur des informations de phase correspondant au coefficient de réflexion, identifier une valeur de différence entre des informations de phase de référence correspondant à la bande de fréquence désignée parmi des éléments d'informations de phase de référence et les informations de phase correspondant au coefficient de réflexion ; et compenser un autre signal de sortie devant être transmis par le biais de l'émetteur-récepteur en se basant au moins sur la valeur de différence. L'invention concerne en outre divers modes de réalisation possibles.
