Title (EN) METHOD FOR ELIMINATING NON-LINEARITY OF SELF-INTERFERENCE SIGNAL IN FREQUENCY DOMAIN AND APPARATUS THEREFOR
(FR) PROCÉDÉ D’ÉLIMINATION DE LA NON-LINÉARITÉ D'UN SIGNAL D'AUTO-BROUILLAGE DANS LE DOMAINE DE FRÉQUENCE ET APPAREIL ASSOCIÉ
(KO) 주파수 영역에서의 자기간섭 신호의 비선형성을 제거하기 위한 방법 및 이를 위한 장치
Abstract:
(EN) An apparatus for eliminating non-linearity of a self-interference signal in a frequency domain according to the present invention comprises a precompensator configured to: receive a reference signal from a baseband transmitting end; perform precompensation on the reference signal by using a self-interference channel function; and transmit the signal to which the precompensation has been applied. The self-interference channel function can be determined using the reference signal and a received signal which goes through a baseband conversion after the reference signal is radiated through a transmit antenna and then received by a receive antenna.
(FR) L'invention concerne un appareil destiné à éliminer la non-linéarité d'un signal d'auto-brouillage dans un domaine de fréquence, comprenant un pré-compensateur conçu pour : recevoir un signal de référence depuis une extrémité de transmission en bande de base ; réaliser une pré-compensation sur le signal de référence en utilisant une fonction de canal d'auto-brouillage ; et transmettre le signal auquel la pré-compensation a été appliquée. La fonction de canal d'auto-brouillage peut être déterminée à l'aide du signal de référence et d'un signal reçu qui subit une conversion en bande de base une fois que le signal de référence a rayonné à travers une antenne de transmission, puis a été reçu par une antenne de réception.
(KO) 본 발명에 따른 주파수 영역에서의 자기간섭 신호의 비선형성을 제거하기 위한 장치는 기저대역 송신단으로부터 기준신호를 수신하고, 상기 기준신호에 자기간섭 채널 함수를 이용하여 선보상을 수행하며, 상기 선보상이 적용된 신호를 송신하도록 구성된 선보상기를 포함한다. 상기 자기간섭 채널 함수는 상기 기준신호와 상기 기준신호가 송신안테나를 통해 방사된 후 수신 안테나로 수신되어 기저대역 변환을 거친 수신신호를 이용하여 결정될 수 있다.
