摘要

数字多载波系统的理论增益受到次优常规相位恢复的阻碍,特别是在光纤传输之后。我们通过实验验证了一种先进的色散感知算法,该算法解决了这个问题,在800G 125 Gbaud 16载波PCS-64QAM下,传输距离超过1800公里,信噪比增益高达0.5 dB。

Maximizing the Performance of Digital Multi-Carrier Systems with Transmission-Aware Joint Carrier Phase Recovery
Theoretical gains of digital multi-carrier systems are hindered by the use of sub-optimal conventional phase recovery, especially after fiber transmission. We experimentally validate an advanced, dispersion-aware algorithm that addresses this issue, achieving SNR gains up to ∼0.5 dB with 800G 125 Gbaud 16-carrier PCS-64QAM, transmitted over 1800 km.
