<p>An embodiment of the present invention provides an apparatus, comprising a transceiver capable of encoding and decoding a unified quasi-cyclic low-density parity-check (QC-LDPC) code structure for variable code rates and sizes using a unified base matrix definition. QC-LDPC codes form a special class of structured LDPC codes whose parity check matrices comprise permutation or, shifted identity matrices. The unified base matrix definition may be a concatenation of multiple square matrices S<SUB>mxRm</SUB> = (S<SUP>R</SUP></p> |
