  • Method and apparatus for encoding and decoding low density parity check codes and low density turbo product codes
    Publication number: 20030033570
    Abstract: A method of and apparatus for encoding a one dimensional input codeword into an output codeword, wherein the output codeword includes an output codeword bit comprising the steps of receiving the input codeword, wherein the input codeword includes an input codeword bit; creating a generator matrix, wherein the generator matrix includes a parity matrix having a plurality of parity bits; combining the input codeword bit and a corresponding parity bit from the plurality of parity bits, thereby generating an output redundant bit associated with the output codeword bit; transmitting the input codeword bit; and transmitting the output redundant bit.
