Abstract

We introduce a precise Tx-side non-linear distortion compensation scheme for higher-order PAM signals, and experimentally show its effectiveness in 28 GBaud PAM-8 and 40 GBaud THP(Tomlinson Harashima Precoding)-PAM6 signals with more than 2-dB power budget improvement.

精确非线性补偿提高IM/DD高阶PAM信号的误码率

针对高阶PAM信号，提出了一种精确的x侧非线性失真补偿方案，并通过实验验证了该方案对28 GBaud PAM-8和40 GBaud THP(Tomlinson Harashima Precoding)-PAM6信号的有效性，功率预算提高了2 db以上。
