Title (EN) OFDM APPARATUS USING THREE-DIMENSIONAL HEXADECIMAL SIGNAL CONSTELLATION
(FR) APPAREIL OFDM UTILISANT UNE CONSTELLATION DE SIGNAUX HEXADÉCIMAUX TRIDIMENSIONNELLE
(KO) 3차원 16진 신호성상도를 이용한 직교주파수분할다중화 장치
Abstract: front page image
(EN)A three-dimensional OFDM apparatus of the present invention comprises: a serial-parallel conversion unit for converting a serial input signal into N parallel input signals; a three-dimensional signal mapping unit for mapping the N parallel input signals on three-dimensional coordinates of a cube-in-cube type constellation, respectively; and a two-dimensional inverse Fourier transform unit for performing an inverse Fourier transform by generating a two-dimensional matrix on the basis of the mapped three-dimensional coordinates.
(FR)La présente invention porte sur un appareil OFDM tridimensionnel qui comprend : une unité de conversion série-parallèle (SIP) pour convertir un signal d'entrée série en N signaux d'entrée parallèles ; une unité de mappage de signaux tridimensionnels pour mapper les N signaux d'entrée parallèles à des coordonnées tridimensionnelles d'une constellation de type cube dans un cube, respectivement ; et une unité de transformation de Fourrier inverse bidimensionnelle pour réaliser une transformation de Fourrier inverse par génération d'une matrice bidimensionnelle sur la base des coordonnées tridimensionnelles mappées.
(KO)본 발명의 3차원 직교주파수분할다중화 장치는, 직렬 입력 신호를 N개로 병렬화하여 변환하는 직병렬 변환부; 병렬화된 N개의 입력 신호들을 큐브-인-큐브형 신호성상도의 3차원 좌표점들로 각각 매핑하는 3차원 신호 매핑부; 및 매핑된 삼차원 좌표점들을 기초로 이차원 행렬을 생성하여 역푸리에 변환을 수행하는 2차원 역푸리에 변환부를 구비한다.
