A method and apparatus of encoding and decoding data using low density parity check code in a wireless communication system

Abstract From the Canadian patent

A method and apparatus for encoding input data using low density parity check (LDPC) code are provided. The method includes encoding the input data using a parity check matrix generated from a first base matrix which is defined for a code rate the first base matrix having predefined matrix element values when the code rate is 2/3 matrix element values including "-1", which indicates a zero matrix having a z max × z max size "0" which indicates an identity matrix having the z max ×z max size and positive integers which indicate a first permutation matrix having the z max × z max size the first permutation matrix being generated by circularly shifting the identity matrix by the positive …
