Abstract: front page image
(EN)The present invention provides a method for compensating for frequency attenuation using adaptive cyclic delay diversity, and a transmitting apparatus and a receiving apparatus using same. More particularly, the present invention provides an apparatus and a method in which a receiver side selects an antenna to apply a cyclic delay on the basis of the phase difference of signals transmitted by a plurality of transmitting antennas, calculates an optimized adaptive cyclic delay value, and provides a transmitter side with the calculated delay value, and the transmitter side performs a cyclic delay transmission on the basis of the delay value, to thereby compensate for the frequency attenuation at a desired frequency band.
(FR)La présente invention concerne un procédé de compensation d'atténuation de fréquence utilisant une diversité de retard cyclique adaptative, et un émetteur et un récepteur utilisant ce procédé. Plus particulièrement, la présente invention concerne un appareil et un procédé dans lequel un côté récepteur sélectionne une antenne de transmission pour appliquer un retard cyclique sur la base de la différence de phase des signaux transmis par une pluralité d'antennes, calcule une valeur de retard cyclique adaptative optimisée et envoie au côté émetteur la valeur de retard calculée, puis le côté émetteur effectue une transmission à retard cyclique sur la base de la valeur du retard de façon à compenser ainsi l'atténuation de fréquence à une bande de fréquence désirée.
(KO)본 발명은 적응형 순환 지연 다이버서티를 이용한 주파수 감쇄 보상 방법과 그를 이용한 송신장치 및 수신 장치, 구체적으로는 수신측에서 다수 송신 안테나의 송신신호의 위상차를 근거로 순환 지연을 적용할 안테나를 선택하고, 최적화된 적응형 순환 지연값을 산출하여 송신측으로 제공하고, 송신측에서는 그를 기초로 순환지연 송신을 수행함으로써, 원하는 주파수 대역에서의 주파수 감쇄를 보상하는 장치 및 방법을 제공한다.
