Abstract
A method for quasi-cyclic low-density parity-check (QC-LDPC) encoding and decoding of a data packet by a lifted matrix is provided, the method comprising: lifting the QC-LDPC code for maximal code length Nand maximal circulant size Zof the base matrix; generating a plurality of optimal values rfor a plurality of circulants Z, Z, . . . , Zbased on the QC-LDPC code lifted for maximal length N, 0≤r≤Z−1; saving the generated plurality of optimal values rcorresponding to the plurality of circulants Z, Z, . . . , Zand a matrix for the QC-LDPC code lifted for maximal length Nin the memory; receiving a current circulant Zfrom the plurality of circulants Z, Z, . . . , Z; selecting a current optimal value rfrom the plurality of optimal values rstored in the memory corresponding to the current circulant Z; and lifting the base matrix based on the current optimal value r.
