摘要

我们提出了一种自适应准循环ldpc编码的多电平调制方案，适用于未来的100gb /s和1tb /s以太网技术。该方案保持奇偶校验矩阵H的码字长度和列权不变，通过改变H的行权和置换块大小来实现码率的自适应。

Rate-adaptive LDPC-coded multilevel modulation with coherent detection for high-speed optical transmission

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.
