摘要

我们证明了一种基于过渡似然解码器的非线性频谱成形方案，包括符号域和似然域反馈，增强了对带宽限制的容容度，并在10km o波段传输中实现了KP4-FEC阈值，其中93-Gbaud PAM4带宽限制非常严重，其中20 db带宽为40 GHz。

O-Band 10-km PAM Transmission Using Nonlinear-Spectrum-Shaping Encoder and Transition-Likelihood-Based Decoder with Symbol- and Likelihood-Domain Feedbacks

We show that a nonlinear-spectral-shaping scheme with transition-likelihood-based decoder including symbol- and likelihood-domain feedbacks enhances the tolerance to bandwidth limitation and achieves KP4-FEC threshold in 10-km O-band transmission of 93-Gbaud PAM4 with very severe bandwidth limitation in which the 20-dB bandwidth is 40 GHz.
