Title (EN) OFDM RECEIVER WITHOUT REORDERING OF SUB-CARRIER AND METHOD FOR PROCESSING OFDM SIGNAL
(FR) RÉCEPTEUR OFDM SANS RÉORDONNANCEMENT DE SOUS-PORTEUSE ET PROCÉDÉ DE TRAITEMENT DE SIGNAL OFDM

Abstract: front page image
(EN)This invention discloses an OFDM receiver that does not require reordering of a sub-carrier and a method for processing an OFDM signal. The OFDM receiver comprises an I/Q demodulator, an FFT processor, a block for correcting fractional frequency errors, a first multiplier, a block for correcting integral frequency errors, a first adder and a second adder. The method for processing an OFDM signal comprises steps of: demodulating a received OFDM signal to an I/Q signal, applying an offset to the I/Q signal, and generating a spectrum signal by quickly Fourier-transforming the I/Q signal to which the offset is applied.
(FR)L'invention concerne un récepteur OFDM ne nécessitant pas de réordonnancement d'une sous-porteuse, ainsi qu'un procédé de traitement d'un signal OFDM. Le récepteur OFDM comprend un démodulateur I/Q, un processeur FFT, un bloc pour corriger des erreurs de fréquence fractionnaire, un premier multiplicateur, un bloc pour corriger des erreurs de fréquence entière, un premier additionneur et un second additionneur. Le procédé de traitement de signal OFDM consiste à démoduler un signal OFDM reçu pour obtenir un signal I/Q, à appliquer un décalage au signal I/Q, puis à générer un signal spectral en soumettant le signal I/Q, auquel le décalage a été appliqué, à une transformée de Fourier rapide.
(KO)본 발명은 부반송파의 리오더링이 필요하지 않은 OFDM 수신기 및 OFDM 신호처리방법을 개시한다. 상기 OFDM 수신기는, I/Q 복조기, FFT 처리장치, 소수배 주파수 오차 보정블록, 제1곱셈기, 정수배 주파수 오차 보정블록, 제1덧셈기 및 제2덧셈기를 구비한다. 상기 OFDM 신호처리방법은, 수신된 OFDM 신호를 I/Q 신호로 복조하는 복조단계, 상기 I/Q 신호에 오프셋을 인가하는 단계 및 상기 오프셋이 인가된 I/Q 신호를 고속 푸리에 변환하여 스펙트럼신호를 생성하는 단계를 구비한다.
