SYSTEM AND METHOD FOR STRUCTURED LDPC CODE FAMILY

摘要

A low density parity check (LDPC) family of codes is constructed by: determining a protograph for a mother code for the LDPC family of codes. The protograph is lifted by a lifting factor to design code specific protograph for a code. The method also includes constructing a base matrix for the code. The base matrix is constructed by replacing each zero in the code specific protograph with a '-1'; and replacing each one in the code specific protograph with a corresponding value from the mother matrix. The LDPC code includes a codeword size of at least 1344, a plurality of information bits, and a plurality of parity bits. The LDPC code is based on a mother code of code length 672.
