Abstract

다중안테나를 이용한 데이터 전송장치를 제공한다. 상기 장치는 정보비트를 채널코딩하고 성상맵핑하여 데이터 심벌을 생성하는 데이터 처리부, 상기 데이터 심벌에 대해 DFT(Discrete Fourier Transform)를 수행하여 주파수 영역 심벌을 생성하는 DFT 부, 상기 주파수 영역 심벌에 제1 전송 다이버시티 기법을 적용하여 제1 전송심벌을 생성하고, 상기 제1 전송심벌에 제2 전송 다이버시티 기법을 적용하여 제2 전송심벌을 생성하는 MIMO 처리부, 상기 제1 전송심벌 및 상기 제2 전송심벌에 IFFT(Inverse Fast Fourier Transform)를 수행하여 SC-FDMA(Single Carrier-Frequency Division Multiple Access) 심벌을 생성하는 SC-FDMA 변조부, 상기 SC-FDMA 심벌을 전송하는 복수의 송신안테나를 포함한다. 상기 MIMO 처리부는 상기 복수의 송신안테나를 2개의 그룹으로 나누고, 상기 제1 전송심벌을 제1 그룹에 맵핑하고, 상기 제2 전송심벌을 제2 그룹에 맵핑한다. 복수의 송신안테나를 구비한 데이터 전송시스템에 있어서 단일 반송파 특성을 보존시키면서 STBC 및 다른 전송 다이버시티 기법을 적용할 수 있어 SC-FDMA 시스템의 구현이 용이해진다.
