Abstract

We propose an adaptive quasi-cyclic LDPC-coded multilevel modulation scheme, suitable for use in future 100 Gb/s and 1 Tb/s Ethernet technologies. In proposed scheme, the codeword length and column-weight of a parity-check matrix H are kept constant while the code-rate adaptation is performed by varying the row-weight and permutation-block size of H.
