Abstract
본 발명은 다중 대역 또는 다중 안테나 전송 모드에서 높은 데이터 전송률과 호환성을 제공하는 송수신 장치 및 그 방법에 관한 것이다.본 발명에 따른 데이터 송신 방법은, 소스부에서 생성된 데이터를 적어도 하나의 대역에 분배하는 단계; 상기 대역마다 분배된 데이터에 대해 오류 정정을 위한 부호화를 수행하는 단계; 상기 부호화된 데이터를 적어도 하나의 안테나에 분배하는 단계; 상기 안테나마다 분배된 데이터에 대해 부반송파를 할당하고 역푸리에 변환을 수행하는 단계; 상기 부반송파에 대응하는 쇼트 프리앰블 제 1 롱 프리앰블을 생성하는 단계; 데이터의 전송모드에 기초하여 시그널 심벌을 생성하는 단계; 및 상기 전송 모드가 MIMO-OFDM 전송 모드인 경우, 상기 시그널 심벌과 데이터 필드 사이에 사용하지 않는 부반송파의 채널 추정을 위한 제 2 롱 프리앰블을 부가하여 프레임을 생성하는 단계를 포함한다. 본 발명의 구성에 따르면, 상기 제 2 롱 프리앰블을 이용하여 제 1 롱 프리앰블에서 사용하지 않는 부반송파의 채널 추정을 수행하고, 상기 시그널 심벌이 포함하는 전송 모드 정보에 기초하여 수신기가 적응적으로 데이터를 수신할 수 있다.
