摘要: Some embodiments include apparatus and methods for encoding message information. Such apparatus and methods can include using a parity check matrix of a low-density parity check (LDPC) code to generate a first matrix having an upper triangular sub-matrix. Parity information to encode the message information can be generated based on the first matrix if a total number of rows of the upper triangular sub-matrix is equal to the rank of the parity check matrix. If the total number of rows of the upper triangular sub-matrix is less than the rank of the parity check matrix, then a triangularization operation can be performed on a second sub-matrix of the first matrix to generate a second matrix. Parity information to encode the message information can be generated based on the second matrix. Other embodiments including additional apparatus and methods are described.
