Patent ID: 8136021

Claim:
A method of coding information for transmission in a mobile communication system, the method comprising: storing a single matrix comprising a first identity matrix having r rows and c columns and a first parity matrix having s rows and t columns; determining a generating matrix according to the single matrix and a code (n, k), the generating matrix comprising a second identity matrix having equal to or less than r rows and equal to or less than c columns and a second parity matrix having equal to or less than s rows and equal to or less than t columns; encoding information bits into codeword for transmission using the generating matrix, wherein a number of coded bits per codeword is n and a number of information bits coded to generate each codeword is k; and transmitting the codeword, wherein the second identity matrix is a subset of the first identity matrix, the second parity matrix is a subset of the first parity matrix and the second identity matrix and the second parity matrix are based on n and k.
