Abstract

We propose a subcarrier-multiplexed four-dimensional LDPC bit-interleaved coded modulation scheme that is capable of achieving beyond 480 Gb/s single-channel transmission rate over optical channels. Subcarrier-multiplexed four-dimensional LDPC coded modulation scheme outperforms the corresponding dual polarization schemes by up to 4.6 dB in OSNR at BER 10(-8).

摘要

我们提出了一种子载波复用的四维低密度奇偶校验（LDPC）比特交织编码调制方案，该方案能够在光信道上实现超过480 Gb/s的单通道传输速率。在误码率为10^(-8)时，子载波复用的四维LDPC编码调制方案在光信噪比（OSNR）方面比相应的双偏振方案性能高出4.6 dB。
