Abstract

디지털 방송 시스템에서 다중 안테나(Multiple Input Multiple Output; MIMO) 전송 방법이 제공된다. 상기 방법은 제1 정보 비트들을 변조하여 복수의 제1 변조 심볼(symbol)을 생성하는 단계, 제2 정보 비트들을 변조하여 복수의 제2 변조 심볼(symbol)을 생성하는 단계, 상기 복수의 제1 변조 심볼과 상기 복수의 제2 변조 심볼을 프리코딩하여, 복수의 제1 프리코딩된 심볼과 복수의 제2 프리코딩된 심볼을 생성하는 단계 및 상기 복수의 제1 프리코딩된 심볼 각각과 상기 복수의 제2 프리코딩된 심볼 각각을 제1 안테나와 제2 안테나를 통해 서로 교차하여(stagger) 할당하고 전송하는 단계를 포함하는 것을 특징으로 한다.
