Abstract:
Concepts and schemes pertaining to quasi-cyclic-low-density parity-check (QC-LDPC) coding are described. A processor of an apparatus may generate a QC-LDPC code having a plurality of codebooks embedded therein. The processor may select a codebook from the plurality of codebooks. The processor may also encode data using the selected codebook. Alternatively or additionally, the processor may generate the QC-LDPC code including at least one quasi-row orthogonal layer. Alternatively or additionally, the processor may generate the QC-LDPC code including a base matrix a portion of which forming a kernel matrix that corresponds to a code rate of at least a threshold value.
