방법 및 장비가 소스워드를 인코딩하고 LDPC 행렬로 코드워드를 디코딩하기 위해 개시된다. 레이트 ½의 길이 1344인 LDPC 코드워드를 생성하기 위한 변조 및 코딩 방식(modulation and coding scheme, MCS)의 예시적 실시예가 설명된다. Methods and devices are disclosed for encoding source words and decoding codewords with LDPC matrices. Example embodiments of a modulation and coding scheme (MCS) for generating a rate 1/2 length 1344 LDPC codeword are described. The method includes segmenting a stream of data bits into 336 bit size segments, adding 336 padding bits to each 336 bit size segment to generate corresponding 672 bit size source words, applying a 1/2 rate low density parity check (LDPC) coding to each 672 bit size source word to generate a corresponding 1344 bit size codeword that includes 672 parity bits; and for each codeword, substituting the 336 padding bits with 336 bits derived from the data bits included in the codeword, to provide a 1344 bit size codeword that includes a concatenation of the 336 data bits, the 336 bits derived from the data bits, and 672 parity bits.
