Method for selecting low density parity check (LDPC) code used for encoding of variable length data

Image Number 8 for United States Patent #7747934.

A method for selecting a low-density parity-check (LDPC) code for encoding variable sized data used in data communication systems. The method selects a LPCD code from a plurality of LDPC codes of different codeword lengths and code rates; by calculating a number of shortening N.sub.shortened bits and a number of puncturing N.sub.punctured bits for each of the plurality of LDPC codes, and determines a selected LDPC code from the plurality of shortened and punctured LDPC codes meeting a performance criterion.
