Claims (10)
- 하나의 타일(tile)이 복수의 데이터 부반송파와 적어도 하나의 파일럿 부반송파를 포함하는 무선통신 시스템에서, 복수의 타일(tile)들로 구성되는 서브채널을 통해 부호어(codeword)를 전송하는 방법에 있어서,상기 복수의 타일들 각각에서 상기 적어도 하나의 파일럿 부반송파에는 파일럿 심벌을 할당하고, 상기 복수의 데이터 부반송파 중 일부의 데이터 부반송파에는 제1 부호어 심벌을 할당하며, 나머지의 데이터 부반송파에는 제2 부호어 심벌을 할당하여 부호어를 생성하는 단계; 및상기 부호어를 전송하는 단계를 포함하되,상기 복수의 타일들 각각은 포함하는 상기 제1 부호어 심벌 및 상기 제2 부호어 심벌에 의해 구분되며,상기 부호어의 비트값은 상기 복수의 타일들의 조합에 의해 결정되는 것을 특징으로 하는 부호어 전송방법.
- 제 1 항에 있어서,상기 서브채널은 6개의 타일들로 구성되고, 상기 부호어의 크기는 6비트이며, 상기 부호어 000000 내지 111111에 대한 변조를 각각 w0 내지 w63이라 할 때, 아래의 수학식과 같은 관계가 성립하는, 부호어 전송방법.wi+16=-wi , wi+32=jwi , wi+48=-jwi , i=0,1,2,...,15
- 제 1 항에 있어서,상기 복수의 타일들 각각에서 상기 제1 부호어 심벌이 할당되는 상기 데이터 부반송파 수와 상기 제2 부호어 심벌이 할당되는 상기 데이터 부반송파의 수의 비율이 1:1인, 부호어 전송방법.
