Abstract:
An LDPC parity check matrix includes a systematic portion having a plurality of systematic elements and a parity portion having a plurality of parity elements. The value of each systematic element determines a cyclic shift to be applied to rows of an identity submatrix corresponding to that element. The value of each parity element determines a cyclic shift to be applied to rows of an identity submatrix corresponding to that element. The weights of two or more columns of the parity portion are the same.

Claim (Index 65):
A method comprising:\n encoding data as a code word, using a digital data transmitter comprising a hardware processor, according to a Low Density Parity Check (LDPC) matrix, wherein:\n the LDPC matrix relates a payload of the code word with a parity to enable a reduction in a number of decoding iterations required by a decoder that receives the code word, \n the LDPC matrix comprises a plurality of elements of a systematic portion and a plurality of elements of a parity portion, \n the length of the payload is the product (\u201cXY\u201d) of a first number (\u201cX\u201d, a positive integer) and a second number (\u201cY\u201d, a positive integer), \n the length of the parity is the product (\u201cXZ\u201d) of X and a third number (\u201cZ, a positive integer), \n the number of elements of the systematic portion is the product (\u201cYZ\u201d) of Y and Z, \n the number of elements of the parity portion is the product (\u201cZZ\u201d) of Z and Z, \n each element of the plurality of elements in the systematic portion and the plurality of elements in the parity portion correspond to a submatrix having X columns and X rows, \n a zero-valued element corresponds to an identity submatrix, \n a positive-valued element corresponds to an identity submatrix with rows that are a cyclically shifted according the positive value, and \n a negative-valued systematic element corresponds to a zero submatrix, and \n two or more columns of the parity portion have an equal number of positive-valued elements.
