- Abstract
- 비트 인터리버, BICM 장치 및 비트 인터리빙 방법이 개시된다. 본 발명의 일실시예에 따른 비트 인터리버는 길이가 64800이고 부호율이 7/15인 LDPC 부호어를 저장하는 제1 메모리; 상기 LDPC 부호어를, 상기 LDPC 부호어의 패러럴 팩터(parallel factor)에 상응하는 사이즈의 비트그룹 단위로 인터리빙하여 인터리빙된 부호어를 생성하는 프로세서; 및 상기 인터리빙된 부호어를 QPSK 변조를 위한 변조기로 제공하는 제2 메모리를 포함한다.
- KSP Keywords
- Low Density Parity Check(LDPC), low density, parallel factor, parity check
